"help" app (yelp) just displays a blank window with "Ubuntu Desktop Guide" title on rpi

[Paul Larson]

I'm using the jammy beta (20220329) image running on an rpi4 8GB
clicking on the "help" app in the dock launches a window with the title "Ubuntu Desktop Guide". The icons for forward/back, bookmarks, search, etc. are all visible at the top of the window, but everything else in the window is just a blank white area. On amd64, however, it seems to work fine.

I also noticed that if I move the mouse around through the area, the pointer sometimes changes, and if I hover there for a second, a tooltip comes up with things like "Start applications" or "Visual overview of Gnome". I can click on these and it seems to take me forward to something, because the back icon is no longer greyed out, but I still can't see any content in the window.
