"Fixes 20133. Fix back navigation after canceled multimedia attachment"

[vinayakkumargupta]

Purpose / Description

Fix back navigation after canceled multimedia attachment in Note editor.

Fixes

Remove the multimedia bottom sheet when in onActivityResult is coming as cancelled. Now Note editor correctly handled back navigation

• Fixes [BUG] 'Add Audio Clip': two back presses are needed to return #20133

Approach

The regression was caused by re-invoking showMultimediaBottomSheet() when the multimedia activity result was cancelled.
This caused the bottom sheet to be displayed again when navigating back, preserving an invalid selection state.
The fix removes the redundant call to re-show the bottom sheet and allows the existing back-navigation logic to proceed normally by handling only the selected multimedia action.
Regression analysis:
First bad commit: 7cc16f7
Last good commit: 2bbcf6b
The issue was identified using git blame and confirmed via git bisect.

How Has This Been Tested?

Open Note Editor
Tap Attach
Select Add Audio Clip
Press Back (cancel selection)
Press Back again
Result
Before fix: Multimedia bottom sheet reappears and selection state remains active
After fix: Returns cleanly to Note Editor with no residual selection

Learning (optional, can help others)

Using git blame together with git bisect helped identify the exact regression commit and understand how navigation state was unintentionally preserved.
