I've been using this plugin for several years without any problem (with tinymce 5 and 6), but it recently stopped working. I've noticed it a few days ago; not sure exactly when it stopped working. Anyway, the current tinymce version is 6.7.3.

The problem seems to be located in the call to the source function. The function is called, but its 1st argument, the query, is always an empty string, so there is nothing to search for.

I guess something must have changed in tinymce, and this change has broken the plugin ?

Anyone has a clue on how to fix this ?
