### Godot version

### System information

Godot v4.2.rc (702227129) - Debian GNU/Linux trixie/sid trixie - X11 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 6GB (nvidia) - AMD Ryzen 5 1600 Six-Core Processor (12 Threads)

### Issue description

Found a consistent crash when calling `hide()` from `_notification()`.
It does not happen if the call is deferred.

### Steps to reproduce

The `hide_test.gd` script has a boolean `cause_crash`. If it is true, hovering the mouse over the label crashes without an error in the Godot Editor Console. If it's false it hides the label as expected.

### Minimal reproduction project
