Block reference clipboard bug on mobile app

Nobody has claimed this yet.

### Search first

- [X] I searched and no similar issues were found

### What Happened?

When pasting text on mobile inside “(())” for a block reference, the text will not search. It only searches When you start typing after initiating the block reference.

### Reproduce the Bug

Create a new bullet on the mobile app. Add the block reference parentheses “(())”. Click into the parenthesis, paste in the text for a block you want to reference. At this point the menu will not search for the block. The only way to search is manually typing after you create the parentheses.

### Expected Behavior

I’d expect to be able to paste text into the parentheses and see the search for the block I want to reference.

No file or test is named. Reproduce the issue on the mobile app by creating a bullet, inserting a block reference, and pasting search text into the parentheses; trace the mobile block-reference input handling. Done means pasted text triggers the block search menu just as typed text does.
