Just discovered a bug in X and Pro for the Navigation Collapsed element:
Issue: menu links only navigate on second click within collapsed section
Location: Navigation Collapsed element’s ‘collapsed’ section
Context: Safari (latest) on iOS
Clicking any item within the collapsed menu requires two taps: the first tap does not affect anything, the second tap functions as expected.
This bug can only be reproduced on iOS devices and does not show when emulating mobile screen widths on desktop browsers. Furthermore, this bug only seems to apply to Safari on iOS possibly due to its specific javascript rendering engine.
If someone could look into this, I’d appreciate that a lot. I’ve noticed this occurring on at least two websites we’ve published and I frankly wouldn’t care if Safari were not the default browser for iPhones which make up a great deal of the target audience
