Title: Sticky note content replaced with "c" when dragging on whiteboard
Description:
When I drag/move a sticky note on a Confluence Cloud whiteboard, the sticky note's content is overwritten with the single character "c". This happens consistently regardless of:
Browser (Chrome, Firefox all affected)
Input method (Chinese IME on/off, pure English keyboard layout)
Keyboard shortcuts enabled/disabled
Steps to reproduce:
Open a whiteboard and create a sticky note with some text
Click the sticky note and drag to move it
Observe: content is replaced with "c"
Expected: Sticky note moves without content change
Actual: Content is replaced with "c"
Environment: Confluence Cloud
