singleTabMode="fullwidth" does not update correctly with drag-n-drop

[vincent-lecrubier-skydio]

Problem
In singleTabMode="fullwidth" , the "fullWidth-ness" of individual tab groups is initially correct, but then is not maintained correctly during the lifecycle:

• It updates correctly when a tab is removed by closing it (If one tab is remaining it becomes full width) 🟢
• Does not update correctly when a tab is removed by dragging it somewhere else (If one tab is remaining it remains non-full width) 🔴
• Does not update correctly when a tab is added by dragging from somewhere else (If there was only one tab is the group such that it was full-width, then after another is added, you now have 2 tabs that are sharing the full width) 🔴

To Reproduce
I'm out of free codesandboxes, but it's super simple to reproduce:

Steps to reproduce the behavior:

1. Use default dockview demo
2. Add singleTabMode="fullwidth" to <DockviewReact/>
3. Move tabs around by drag n drop

Expected behavior
The "fullWidth-ness" of individual tab groups remains correct
