Cannot select labels in viewer

Describe the Bug

As a user I want to select labels in a BPMN diagram (viewer distribution). It works sometimes, but really not reliably:

Steps to Reproduce

1. Open viewer starter
2. Try to select labels via double-click

Expected Behavior

All labels can reliably selected via double-click.

Environment

• Browser: Chrome 100
• OS: Windows
• Library version: v9.0.1

Root cause of the issue seems to be that we stack a djs-hit rect on top of the text. Adding the following styles does workaround this issue:

.djs-hit {
  pointer-events: none;
}
