Seems to occur mostly when editing text strings. Also happened in Edge.
Does this still occur without other plugins active? It’s possible another plugin is interfering with the CodeMirror editor.
As I am not the primary maintainer of this WordPress site I am not at liberty to disable all the other plug-ins.
I have taken careful note that it only occurs when I am editing a double quoted text string with embedded variables encased in {}. It only happens when I edit an existing string, not when I am entering a new one.
Fair enough, I wasn’t sure if you had a test site handy you could try that on.
Thank you for the extra information, I’ll do some testing and see whether I can reproduce the problem.
In version 3.0 we are switching to using the WordPress-bundled code editor library, so that should hopefully fix this problem when it’s released.
