### Godot version

Master, commit 37d1dfef9d81aade2

### System information

PopOs 22.04, Any renderer, NVIDIA Corporation GP107GLM, Driver Version: 525.89.02

### Issue description

On the GLTF import screen, when you hover the mouse cursor over any property, the tooltip only flashes for a split second, making it very hard to read.

This does not happen in other areas of the editor, like when hovering over a property in the node inspector.

- Double click a GLTF File to open its `Advanced Import Settings` screen
- Hover over any property
- The tooltip will quickly flash then vanish

### Minimal reproduction project

You only need to have GLTF file in any project.
Here is one :
