[Bug] Two finger scrolling on touchpad opens link dialog

[gaul]

Steps to reproduce

• Open a page with many links, e.g., https://en.wikipedia.org/wiki/Firefox
• Scroll with 2 fingers on touch pad until the pointer end up resting on a link.
• Remove both fingers.
• Then use a single finger on the touch pad to move the pointer a little but leave it pointing at a link when you lift your finger.

Expected behavior

Expectation is that the pointer simply is on the link but no clicking has occurred.

Actual behavior

Unwanted click is generated.

Same issue here with Lenovo Chromebook Flex 5i, CrOS 91.0.4472.114, Android 11.
Also my reported issue where I can't create new collections, cause the enter key hasn't any function:
