PodNotes view is blank on mobile when opened from the sidebar #505

On a phone, the PodNotes view in the right sidebar is blank. Choosing Podcast Player in the sidebar's view picker shows an empty page, and restarting Obsidian doesn't help. Running Show PodNotes from the command palette (or the ribbon icon) makes it appear.

Reported on iOS with 2.22.0 from the community plugin list.

Likely cause: on mobile, PodNotes keeps a restored view dormant at startup (src/main.ts, podcastViewMountEnabled, from #208), and only activateView() (the command, the ribbon, a URI) mounts it. Revealing the leaf through Obsidian's own sidebar picker never does, so the view stays empty until a command runs. 2.21.1 has the same gate.

Expected: the view shows its content whenever it's opened, however it's opened.
