Crash on http://acelookup.cobradragon.com when mousing over text input
I experience a regular crash when visiting http://acelookup.cobradragon.com. To reproduce, mouse over the text field at the center of the screen. It crashes every time for me on Debian 12 w/ the QT chrome.
Here is the log.

WebContent process crashed!
FontDatabase::load_all_fonts_from_uri('file:///home/adam/.local/share/fonts'): open: No such file or directory (errno=2)
I tried creating the folder at /home/adam/.local/share/fonts but that doesn't resolve the crash and seems unrelated.
It's caused by this assertion: https://github.com/SerenityOS/serenity/blob/6602b1ddb196cdefcbdc550cd2e4d28830f9769b/Userland/Libraries/LibWeb/Layout/Node.cpp#L250
Removing the assertion makes the site work. Which leads me to believe the assertion might be wrong here?
