Thank you, and my apologies – I should have mentioned, our testing has been performed in our development environment, which has already been updated to 5.7.1. All the issues I described are present in the latest version. And these are issues with the accordion element, not the tab element. I’ll open a feature request!
It must only be an issue at smaller screen widths. When I use Chrome DevTools to emulate a screen width of 2650px, it looks fine. Once you get down to about 1600 it starts getting awkward, around 1400 I’d say it starts getting hard to use. Between about 1300 and 1151 is the worst, which is the range that my laptop screen is in. At 1150 it hits a breakpoint that puts it back into awkward but usable territory.
Site and credentials in private comment! This is a lower environment, not production. We’re using a child theme, but I switched it to the base Enfold theme for you (the issue occurs either way). So if the front end looks broken, that’s probably why. Shouldn’t affect the back end where this issue is, though!
Thank you so much for your help!
