mouse cursor no longer changes over hyperlinks in Firefox on OpenBSD 7.5

Hello,

I'm not sure if this is expected behavior or not, but it seems that
after upgrading to OpenBSD 7.5 the mouse cursor no longer changes from
an arrow pointer to a hand when I hover over links in Firefox. It does
work for some other programs though. Also, moving the mouse over other
elements (like text entry) does work. It's just moving over links that
no longer visibly changes the mouse cursor.

Is this a problem isolated to Firefox? Is anyone aware of a change
that would cause this and more to the point, how to recover the
functionality?

Thanks,

Andy
