incorrect commit graph (steps to reproduce available)

[sitaramc]

Describe the bug

Commit graph shown is incorrect when using "--all" and "date order".

To Reproduce

Prep:

git clone https://codeberg.org/sitaramc/gitolite
cd gitolite

for i in ssh-certs-extra-code demo-sha256-method-1 demo-sha256-method-2 sha256-support termux-changes namespaces UTF-8 g2
    git checkout -b $i --track origin/$i
end

git checkout master

Run lazygit here, then

4               # commits
_               # full window
Ctrl-L, then "toggle show whole git graph"
Ctrl-L again, then "Commit sort-order" -> Date-order

Now page down till you hit tag "v3.6.3". The 4 commits above it (i.e., its children) should actually look like this (this is extracted from git log --graph --all --oneline):

    * 8bef671 (minor) fix typo
    | * 813eee0 (origin/UTF-8, UTF-8) speed problems...
    | * ad7c2e5 (utf8) enable utf8 for ref or filename checks
    | * adfa76d (utf8) prepare for utf8 handling
    |/
    * 5d24ae6 (tag: v3.6.3) v3.6.3

Instead, lazygit makes it look like

    * 813eee0 (origin/UTF-8, UTF-8) speed problems...
    | * ad7c2e5 (utf8) enable utf8 for ref or filename checks
    | * adfa76d (utf8) prepare for utf8 handling
    | * 8bef671 (minor) fix typo
    |/
    * 5d24ae6 (tag: v3.6.3) v3.6.3

However, this bug does not appear if, after hitting "4" and "_", you do things in this order:

Ctrl-L again, then "Commit sort-order" -> Date-order
Ctrl-L, then "toggle show whole git graph"

Expected behavior
