Plugin manager selection jumps when using mouse

[3351163616]

What happened?

In the TUI plugin manager, opened via the command palette and Plugins, the highlighted row can jump when moving or clicking with the mouse. Keyboard up/down selection does not show the same behavior.

Steps to reproduce

1. Open the command palette.
2. Select Plugins.
3. Move the mouse across the plugin list or click entries.

Expected behavior

The highlighted row should stay under the hovered/clicked plugin without causing the list to scroll unexpectedly.

Notes

The plugin manager feeds DialogSelect hover movement back into current, which causes the dialog to re-center the list while the mouse is still over it.
