Podcast Overlay has wrong dimensions

The podcast swipe up panel has wrong dimensions.

How to reproduce:

- Start Podcast in List View
- Go in Detail View (See that the podcast panel has margin on the bottom)
- Go back to the List View
- Verify that there is a black area above the podcast area where no list items are visible

Start by reproducing the listed navigation sequence in the Android client and inspect the podcast swipe-up panel as it transitions between detail and list views. Done means the panel has correct dimensions in both views, with no bottom margin or black area hiding list items.
