Hey Sam I can’t reproduce it on chrome desktop or android chrome, my first guess would be that you need to clear your browser cache.
Check it on multiple devices. See if it’s only happening on a specific page. If you can reproduce it consistently across multiple devices let me know how to find it.
It’s probably a small fix, but these tend to take a bit of time in the R&D aspect around identifying the cause of the problem and figuring out how to prevent it.
Surprised you aren’t seeing it on chrome mobile. To reproduce it, are you triggering the mobile slideout, then either clicking the X or empty space that should close it?
I’m getting the issue on chrome and safar. See screenshots. Chrome
