This is useful to remove any handlers, e.g., when submitting an exercise. Hopefully, we will see less Javascript errors due to cumbersome behavior with these changes...
Also, I am cleaning up unused event handlers. The `showOutput` method doesn't seem to be used, we should observe this in the future.
Closes CODEOCEAN-KQ
Even though the error occurs not very frequent, we want to resolve it. Sentry identified that the former error still occurs and we try once more to fix it.
Fixes CODEOCEAN-JH
Even though not reproducible locally, we had some errors captured through Sentry where the Tooltip was opened on the (already hidden) run button. This resulted in an error by the Bootstrap library. Most likely, the issue was caused by some race condition.
Fixes CODEOCEAN-BA
Previously, removing an UTF-16 character (such as emojis) required pressing the backspace twice. This was caused by ACE only handling single UTF-8 characters.
Fixes CODEOCEAN-GC
Hypothesis: When unloadAutoSave was called, we first saved (causing this.autosaveTimer to become null) and then tried to clearTimeout on this variable (= on null). This probably never worked?
Hopefully closes CODEOCEAN-B5
Previously, a user-defined test (those run with "Test" instead of "Run") would cause a flash message and a Sentry error if anything was printed to StdErr. As this might happen during user code execution (and therefore is no error), we remove this warning. All existing errors are already caught (compare with enum status in testrun.rb), so it's fine for now.
Fixes CODEOCEAN-BT
* The `render` command is not used much
* Originally added with commit 898074be3f
* The `#render` anchor (see findOrCreateRenderElement) was the "Render" button above the editor, nothing was rendered at all if executing code and otherwise it would be included _within_ the button.
