Platform: Windows 11, Chrome
When editing a post in WordPress, with the GuideJar extension active, there is a div added to the post:
<div id="guidejar-container" style="position: fixed; width: 0px; height: 0px; top: 0px; left: 0px; z-index: 2147483647; overflow: visible;"></div>
Obviously this is a breaking bug. I've deactivated the extension.
