Hello Ryan,
A customer asked me how to delete a microdata. While taking screenshots to show him, I saw that the tag containing the type doesn't clean up properly, it remains what precedes the type. Tested on Firefox and GChrome.
Example:
<p itemscope="itemscope" itemtype="https://schema.org/">...</p>
I also noticed that it is not possible to use the scrollbars to scroll through the types or properties, the dropdown list closes as soon as I click on the scrollbar or one of the arrows.
