249-250: Apply the same workaround toanimateToBoundsfor consistency.The
animateToBoundsmethod usesthis.element.widthandthis.element.heightdirectly without checking for the uninitialized 300×150 state thatfitToBoundsguards against. SinceanimateToBoundsuses the same zoom calculation formula and can be invoked viagoToNode()during user interaction, it could exhibit the same extreme zoom issue if the canvas hasn't been properly rendered yet.

Learning: In the ComfyUI_frontend project, Zod is on v3.x. Do not suggest Zod v4 standalone validators (z.uuid, z.ulid, z.cuid2, z.nanoid) until an upgrade to Zod 4 is performed. When reviewing TypeScript files (e.g., src/platform/remote/comfyui/jobs/jobTypes.ts) validate against Zod 3 capabilities and avoid introducing v4-specific features; flag any proposal to upgrade or incorporate v4-only validators and propose staying with compatible 3.x patterns.

Learning: In the ComfyUI_frontend repository, lint rules require keeping 'import type' statements separate from non-type imports, even if importing from the same module. Do not suggest consolidating them into a single import statement. Ensure type imports remain on their own line (import type { ... } from 'module') and regular imports stay on separate lines.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: This repository uses CI automation to format code (pnpm format). Do not include manual formatting suggestions in code reviews for Comfy-Org/ComfyUI_frontend. If formatting issues are detected, rely on the CI formatter or re-run pnpm format. Focus reviews on correctness, readability, performance, accessibility, and maintainability rather than style formatting.

#7435 introduced a tricky regression which will cause extremely small levels of zoom with nodes spread far apart when in vue mode. I am able to consistently reproduce this behaviour by - Being in vue mode - Swapping to a different tab so that ComfyUI is in the background - Making a pointless line change to frontend code so that vite forces a reload - Waiting ~1 minute to ensure the reload completes - Swapping back to the ComfyUI tab From testing, if a reload occurs while the tab is backgrounded, the canvas has an uninitialized size of 300x150. This PR proposes falling back to a more sane default width and height of 1920x1080 if it is detected that the canvas element is unitialized. | Before | After | | ------ | ----- | | <img width="360" alt="before" src="https://github.com/user-attachments/assets/8e19fc98-7187-4008-98cc-fb5ea3bcdce2"/> | <img width="360" alt="after" src="https://github.com/user-attachments/assets/add88614-3451-44df-ae9a-b0b867486459" />| This appears to have consistently good results, but second opinions or further testing would be appreciated. A more reasonable option (like skipping this automatic fitView if the canvas has uninitialized size) is likely to be safer, even if it results in a return of edge cases resulting in a graph having no nodes in view after load. ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-7751-Workaround-for-reload-causing-node-spread-2d36d73d365081b9ae74d5f0e6f436f5) by [Unito](https://www.unito.io)
