I've been working with the admins on the [[w:c:residentevil|Resident Evil Wiki]], trying to make their tabs mobile friendly. I came up with a pretty good solution, however when moving to another tab, the images don't show right away. Once the user begins scrolling, then the images show. If the user then goes back to a previous tab, the images show just fine.
Here's my test page: https://residentevil.fandom.com/wiki/User:Ferretwings/Tabber_experiment (a misnomer, as I'm not actually using tabber)
