Title:
Unresponsive window when opening brush or color picker popup

Status in MyPaint:
Unknown
Status in mypaint package in Ubuntu:
Triaged

Bug description:
### Description of the problem

The whole window becomes unresponsive when you open the brush or color
picker popup window. The workaround to recover from this condition is
pressing ESC once.

The screen recording added below will also show you another problem.
Most of the time I can't pick another brush. Sometimes it works, but I
can't consistently reproduce it. This may or may not be related to the
frozen window situation.

### Basic system details

Operating system: Ubuntu 21.10 impish (amd64)
Desktop environment: GNOME (wayland)
MyPaint version:
Package mypaint from universe repository

$ mypaint --version
INFO: mypaint: Installation layout: conventional POSIX-like structure with prefix '/usr'
MyPaint version 2.0.1+gitexport.478280f

### Steps to reproduce

Start mypaint.
Click the large brush selector at the bottom right, or the color selector at the bottom left.
The popup brush selector window appears, but the whole window is now unresponsive.

It's a little difficult to show you what's happening without a
keypress indicator, but it's mostly me clicking around and pressing
ESC to unfreeze the application window. You can tell it's frozen by
paying attention to the cursor.
