Low priority does nothing for DMs

[LinAGKar]

Describe the bug

If you mark a room as low priority, it's moved into under the low priority header at the bottom, separate from the non-low priority rooms. In Element-web, low-priority DMs are also moved to the same place. In Element-Android however, marking a DM as low priority doesn't do anything; low priority DMs are still mixed in with the regular priority DMs.
