[iOS PWA] Toolbar activates on dismiss alert

[raineorshine]

When swiping to dismiss an alert, toolbar buttons underneath the alert are activated.

Reproducible on iOS Safari in PWA mode. Cannot reproduce in normal mobile Safari or in emulated mobile on Chrome.

It also may be possible to activate the cursorBack gesture. Make sure gestures are disabled during swipe to dismiss.

Steps to Reproduce

• a
• b
• c

1. Set the cursor on c.
2. Tap the Archive button in the toolbar.
3. Swipe to dismiss the alert, starting the swipe at the bottom of the Archive button and ending at the top.
