Bookmark Folder Arrow Animation Bug

[bigscheming]

I've noticed a minor issue with the animations of the drop-down folder arrows in bookmark manager.
This happens when closing an expanded folder (folder 1) that contains a closed sub-folder (folder 2).
If you have another open folder (folder 3) listed underneath "folder 1," upon closing the "folder 1" the arrow icon next to "folder 3" will be shown turning from sideways to downwards, as if it were one of the closed sub-folders that had previously occupied that line.
This can be seen in reverse on "folder 2" when closing "folder 1" again.
If anyone wants to see this but can't recreate it I can record it and share here as a gif.

@bigscheming It was confusing for me, so I tried to recreate it.

Here is a recording of what I found (slowed down):

Is this what you are talking about? If so, then I think the solution for this could be pretty simple.

Here is the CSS that currently controls the animation:

.vivaldi-tree .tree-row .expand-icon svg {
    transition: transform 100ms linear;
}

If it were changed include hover like this:

.vivaldi-tree .tree-row:hover .expand-icon svg {
    transition: transform 100ms linear;
}

Then it would be solved. I don't believe there would be a downside to limiting the animation to the hovered bookmark folder. Can anyone think of an edge case where this could break something?

Here is a recording with the new proposed CSS (slowed down, sorry for the slight GIF artifact around the arrow):
