delay in popup causes keystrokes to go to editor

In the past (I'm not sure when it changed, but it's fairly recent, maybe 2-4 months ago?), when you request a popup dialog, eg double click shift, any keypress that you made while waiting for the popup didn't have any effect until the popup was shown and then the key were entered into the input field of the popup.

Now if the popup is not immediately shown for some reason, eg. computer is currently a bit slow due to swapping, the keys entered go to the editor. This is extremely annoying and was one of the reasons for me to drop netbeans and move to Intellij.

Is there a simple fix to change this?
