[EXPERIMENTAL] Fix Select word with double click

@RaymondLim can you test this?  It's the easiest solution I can think of and it does work.  I'm curious if it works for you 

This is for #9040 
180 was the smallest delay I could get it to not pop up in the middle of a double click. I tried 160 and it wouldn't work. The pane was activated too soon.  It has to do with how codemirror recognizes double clicks. It checks the time between left clicks and 2 clicks have to be within 400ms of each other at the same location.  it's unfortunate that it activates (focuses) the editor which activates the pane which kicks in the lint which stifles the mouse location between the first and second click.  I guess we should make the delay either 400ms or somehow communicate that the double click has completed.  

We could make it 400ms but that would be really slow.  I was thinking that using the browser's `dblclck` event the mouse position wouldn't need to be checked and code mirror could use that to perform the selection.  Not sure though if that would make a difference.  The popping up of the panel between the 2 clicks is sort of jarring and may stifle the browser as well.
