Space filter ignores direct chats

### Steps to reproduce

Click the space filter in top right corner and select a space.

### Outcome

#### What did you expect?
List of all rooms of the space and direct chats with people from the space (as in element web)

#### What happened instead?
You get only the rooms of the space but not the direct chats.

If this is intended, could you consider adding an option to settings to controll this behaviour?

Start by reproducing the issue through the space filter in the top-right corner on Android, using the reported Pixel 8 and application version 26.06.4 details as context. Trace the space-filter flow and compare its results with Element Web; done means a selected space lists its rooms and direct chats with people from that space, or clearly exposes the intended setting.
