In the inline editor (eg. task description), the inline bar of an
element (eg. link or image) has higher bootstrap z-index than modal that
can be opened via this bar (eg. croping window for an image, link
editing for a link).
So the bar would be over the modal opened by the bar which is
unexpected.
This was solved in 12.3 f2969923 by setting the inline bar to z-index of
$o-wysiwyg-zindex (defined to 1000).
This is the equivalent of 12.0 #37119 fix.
