Can indeed reproduce, thanks for reporting.
At the moment we are bound to a tweaked (and fixed) version of the Ace editor, which comes with many bugs and weirdnesses (in short, it is expected to allow our automatic-indentation mode, but provides no way to control concurrent operations, hence race conditions such as the one you are reporting).
The proper fix for this will probably be to plug-in a more modern and more reliable editor in place of Ace here, but that will require quite a bit of work.
