Toolbar: 'Uncaught TypeError: a._activePosition is undefined'

When clicking toolbar dropdown in Firefox 88.0 (64-bit), I get a ‘script error’ on your own demonstration snippets, for example see

JavaScript debug console reports the following error:

Uncaught TypeError: a._activePosition is undefined

Note that this also seems to happen with drop-down menus on the Ribbon control as well - same JS error.

Is there an official place for bug reports?

Thank you for your note. This is a known problem.
It will be fixed in the next update.

The porblem was fixed in the latest (7.1.8) dhtmlxSuite update.
Now it should work correctly.
Thank you for your report.

Great, thankyou! I will check that out right now …

I think there may be a problem with this forum website - my original post above has been marked as spam and hidden from view?!

Seems to display well for me.

I think this must have been a temporary failure with this forum software, as it is displaying fine for me now as well…:man_facepalming:
