Version 2.3.0 (free) appears to have a bug under certain conditions. When you press the Esc key to close the lightbox, the browser page freezes. You have to F5 to reload and unstick it. The X button on the lightbox (top-right) works fine. The problem appears to relate solely to the use of the Esc key.
This initially happened on a development environment (so not publicly-accessible): Windows 11 Home 23H2; Wampserver 3.3.6 (Apache 2.4.51, PHP 7.4.26); WordPress 6.6.1 (twentytwentytwo theme 1.7). I’ve updated the plugin twice, rolling back in between, and the problem has occurred on each occasion.
I have also updated our production environment: LiteSpeed (Apache 2.4.62, PHP 7.4.33); WordPress 6.6.1 (twentytwentytwo theme 1.7).
UPDATE: The specific issue is that the page vertical scrollbar disappears after the use of the Esc key. Buttons on the page can still be clicked etc.
Browser tests: Chrome 128.0.6613.85: fails on both dev & live instances; Microsoft Edge 128.0.2739.42 fails on dev but NOT on live.
Both instances have a custom CSS directive to force the scroll bar on – body {overflow-y: scroll !important;} – but removing this does not change the behaviour.
