Steps to reproduce

  1. On iPad, enable the core plugin Outline.
  2. Open Outline in the right sidebar.
  3. Pin the right sidebar so it stays open.
  4. Open a note with multiple headings and body text.
  5. Place the cursor somewhere in the editor.
  6. Use a Magic Keyboard trackpad or an external mouse.
  7. Select any heading in Outline to jump to that section.
  8. Click somewhere else in the editor body text.

Expected result

A normal single cursor placement in the editor, with no text selected or jump.

Actual result

A text range is selected unexpectedly in the editor, even though I only performed a normal click.

The selection appears to extend between a random cursor position and the new click position.

Additional information

  • This happens on iPad when returning from Outline to the editor using a trackpad or external mouse.
  • It does not happen when using touch only.
  • It does not happen when the right sidebar is not pinned.
  • It does not matter whether the heading in Outline was selected by touch or by pointer. The trigger is the pointer click back into the editor.
  • It reproduces with both a Magic Keyboard trackpad and an external Bluetooth mouse.

The video shows that after clicking a heading in Outline, the next pointer click in the editor creates an unintended selection.
