ColorPicker SpinBox makes the cursor disappear on drag

[KoBeWi]

Godot version

255e077

System information

Windows 10 x64

Issue description

Dragging the value is not possible. You need to press Escape or click somewhere away to make the cursor appear. Does not seem to happen with SpinBoxes in other places. Only happens in the editor, runtime ColorPickers are fine (related to popups?).

Steps to reproduce

1. Open any ColorPicker in the inspector (e.g. for modulate property)
2. Try dragging SpinBox arrows

I was able to replicate this on Windows 10 and version c80540f

I remember this happening with the GraphEdit spinbox it has for changing zoom (can't find the issue), it was then fixed for spinbox at some point.
