Hi.
Thanks for pull request.
Unfortunately, I was not able to reproduce problem with tabs switching glitch on any tests that we have.
For example tabs_with_dynamic_height or div_tabs.json.
Could you please provide json or specify additional prerequisites for bug reproducing.

Hi!
I've prepared a sample: https://gist.github.com/nice77/de5b9198216dc81674a991367ed61e5a
DivKit version: 32.26.0
iOS: 18.6 (if relevant)

I've also attached screencasts. The first one shows my sample JSON reproducing bizarre behavior, and the second one shows div_tabs.json

I tried to compare two layouts; the issue with switching tabs is happening only when we're using "type": "gallery" inside of a item builder, instead of using "type": "container". Here's my sample with changed type: https://gist.github.com/nice77/309111b7502fb1b60553bc5728aeda41

Yes, thanks a lot.
Now I can reproduce the problem.
I will check couple edge cases today and If everything goes well, we'll merge the PR.
