P: iPad 9.5.0 White Balance picker Impossible to select

I can't select the white balance, using the picker.

After clicking on the White Balance picker, any move to go graph it result in it disappearing.

Lightroom 9.5.0 793255/164

iPad M4 Pro 13 on 17.6.1

Reproduced with: Magic Keyboard trackpad + Pencil Pro.

Only way to work: using fingers.

Basically, anything recognized as mouse movement (which the new Pencil Pro does when hovering) will cancel the picker.

iPad M1 Pro 12.9: reproduced as well using external mouse.

Video attached. First 2 tries: Pencil. Last: trackpad.

Edit: i'm almost sure I selected "bug" when posting, but it doesn't seem to have kept it. If somebody can change it to Bug, thanks.
