→Restoring formula visibility to 50+ tasks for Chrome, IE/Edge, Safari etc
Line 726:
: I will periodically (maybe once a month ?) run an HTML scan to pick up any newly invisible cases. Invisible graphic elements (server-side formula graphics) can be detected by searching through the wiki-generated HTML for the pathological string "exheight" – an undelimited conflation of two attribute names, which leaves the affected graphic with zero height.

:: The moral of this sad episode is that FireFox is out on a limb in its handling of '''<math>''' tags – they do things differently there.
:: (Local font-based MathML processing, rather than the usual font-independent display of server-side formula graphics).
:: Previewing '''<math>''' tag contents in Firefox gives no indication of how things really appear on the majority of browsers. If you do edit in Firefox, you '''must always''' also test the real effects of your edit in either Chrome, IE/Edge, or Safari.
:: Any one of them will do. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 11:24, 25 November 2016 (UTC)
