Caused by rBaa71414dfca7: Fix click-drag events for dragging markers

Short description of error
When click-dragging across the visibility icons (or what they are called) in the Outliner to e.g. change the visibility and the selectability with a single mouse click, Blender instantly crashes / closes.
This must be a rather new problem, might be related to this https://developer.blender.org/T96120

Exact steps for others to reproduce the error

  • Open Blender (very latest master)
  • Go to Outliner and click-drag across the visibility icons of the default cube or the camera:

  • Crash

I can't redo this, tested f74249eaf435dd7e7e71feaf9c996a96e83448e4 and c23ec04b4e30f300a670f1cb1dc882e0608d09ad.

  • Does this happen with factory settings?
  • Does this crash both single-click and dragging? (the report mentions both)

Yes it happens with factory-startup, too.

It doesn't happen when I single-click each of the icons one after the other. It happens only when I click and hold / drag across several of them. For example, if I click on the selectability icon, hold the mouse button and drag it to the right.
