Android selection drag handle gets stuck

[lishid]

Describe the issue

When dragging the drag handle to select text, sometimes it gets "stuck" and can't be moved anymore. Seems to happen more often if you move the drag handle quickly.

I can reproduce this. It seems to be related to highlightSelectionMatches causing DOM changes around the selection (adding the wrapper nodes that do the highlighting), which somehow causes Chrome to decided the drag needs to be aborted. The only solution I was able to find was to turn off highlightSelectionMatches.
