Expected Behavior
On devices that support touch interactions, those touch interactions should work consistently throughout the GUI.
Actual Behavior
On a Windows laptop with both a trackpad and a touchscreen, I found that almost all GUI touch interactions stopped working (for example, I could not use touch to open menus, press the green flag, stop or full screen buttons, select a tab, select a sprite, etc.). All interactions with blocks continued to work by touch as normal.
I got into this state by playing a chord using multitouch on the music extension's note picker piano.
The code for mouse and touch events on the note picker field is in the blocks, but because the effects of the bug are here instead (and not in the blocks!) I'm filing the issue here.
Steps to Reproduce
- Use a windows laptop with a touch screen
- Add the music extension
- Drag out a "play note" block
- Click in the note number field to open the note picker piano
- Play a chord by touching the piano with multiple fingers at once
- Note that you can no longer use touch to interact with GUI elements
