Switching editor takes priority over (un)fold button

[Flexo013]

Current behavior

On a markdown note clicking the fold or unfold arrow causes a switch to editing mode rather than just folding or unfolding.

Expected behavior

The editor mode should not be switched to when clicking the (un)fold arrow.

Small side note: Performing a long click on the arrow does perform the expected behavior.

Steps to reproduce

1. Have a markdown note, with a fold HTML block.

<details><summary>Test summary.</summary>
Test body
</details>

2. Make sure to use the toggle mode view (not the side by side view).
3. Click the (un)fold arrow.
4. It switches to the editor mode.
