Cannot use "Select All" on iOS

[louisatome]

When I try to use the "Select All" button from the long-press contextual menu on iOS, the cursor goes to the end of my script but my text isn't selected.
The problem appears in the version 5.25.0.
If you want to try it :

• Fiddle with version 5.24.0 when it worked : https://jsfiddle.net/az1ke5zz/3/
• Fiddle with version 5.25.0 when it doesn't work anymore : https://jsfiddle.net/az1ke5zz/4/

After some deeper research, it looks like the commit that broke the functionality is 1d00df9 and more specifically the removal of the following CSS :

.CodeMirror-gutter-wrapper {
  -webkit-user-select: none;
  -moz-user-select: none;
  user-select: none;
}

What was the reason for removing it ?

Interested in this as well. Seems like add that back in fixes the issue.

I cannot answer your question, but we are working on a rewrite (CodeMirror 6) that will overhaul input handling and could address this issue. We are currently raising money for this work: See the announcement for more information about the rewrite and a demo.

Note that CodeMirror 6 is by no means stable or usable in production, yet. It is unlikely that we pick up this issue for CodeMirror 5, though.
