Description

When navigating through the issue list on mobile and touchscreen devices you can't scroll when touching the dropdown menus. Instead, the touch down event leads to opening the dropdown menu, making it impossible to start a drag gesture around that area.

Screenshots

Starting to drag in the red bordered area opens the dropdown menu making it impossible to touch there to start dragging down.

Possible resolution?

I observed this issue on many touch input enabled applications, whenever they use the "touch down" event as a trigger. While this works well for mouse operation, this is impacting touch input heavily. Therefore lots of libraries support input gesture detection like "touched" or "clicked" - otherwise combine "touch down" and "touch up" events to detect "touched" and separate it from "touch drag".

Maybe the triggering event may be changed for these dropdown menues?
