Fix for effects bottomsheet flickering to the expanded state while being dragged

[VGJohn]

Description

Effects bottom sheet flickers to the expanded state as the user drags the bottom sheet. The ensureExpanded() function is called when the player state changes which can cause the bottom sheet to expand while being dragged. Updated the BaseDialogFragment to monitor the dragged state of the bottom sheet and skip setting the expanded state if the user is actively dragging the bottom sheet.

Fixes #571

Testing Instructions

1. Play any podcast episode
2. Tap on playback effects to open the bottom sheet
3. Drag the bottom sheet down as seen in the issue
