### Godot version

v4.1.stable.official [970459615]

### System information

Windows 10

### Issue description

Changing a RichTextLabel's text property while dragging the scrollbar causes releasing the mouse to not actually prevent further dragging. Technically it's more pervasive than this since the scrollbar stops reporting other mouse input events (stops being highlighted when hovered, can't release) in general when updating every frame. This works fine for 3.5. This is still broken for 4.2dev3.

### Steps to reproduce

Change a RichTextLabel's text property while dragging the scrollbar. MRP attached.
