Drop position flickers when adding a window to a group with many tabs

Windows Version Number: Windows 11 26H2
App Version: Groupy 2.31

When a group has enough tabs that they fill the whole bar and start shrinking to fit, dragging another window into it gets jumpy. The spot where the new tab is going to land keeps flickering between positions and it's hard to drop it where I want.

Steps:
1. Make a maximized group with a lot of tabs, around 12 or more on a 1920 wide screen, so the tabs are already squeezed
2. Drag another window onto the group and hold it there
3. Watch the tab bar, the insert position keeps jumping around

With only a few tabs in the group it's fine, so I think it's related to the tabs resizing. My guess is that when the preview tab gets added the other tabs shrink, that moves the position under the mouse, so it picks a different slot, they resize again, and it loops.

I have "Use the entire window as a drag and drop target" turned on if that matters.
