Web games are not having their canvas elements rendered

[bradenbest]

Itch version: 25.5.1 x64-64 Windows

The itch app is not rendering my game correctly. I filed two separate issues about the lack of secure context (#2859) and the lack of a javascript console (#2860), but neither of those issues are what's causing my game to not render at all in the itch desktop app.

Main menu

In-game, nothing is rendered

In-game console shows no errors (note the version number)

In-game in firefox (note the version number)

After fighting with this for several hours last night, I've come to the conclusion that the problem is the itch app itself. My reason for believing this is that after I rolled it back to v1.7.7, it was still broken until it randomly decided to work. In that brief window when v1.7.7 was working, v1.8.7 was also working in the itch app. And then I uninstalled v1.7.7 and v1.8.7 broke again with no changes being made to it. This plus the fact that the game works perfectly fine everywhere else tells me that there is no issue with my code--the problem lies upstream with the itch app.

Please mark this bug as high severity.
