fix: Support MacOS trackpad with tap-to-click

[mister-ben]

Description

If a MacOS trackpad is using "tap to click", the tap/click was being ignored by the seek bar sometimes, so there would be no seek. This is because the mousedown MouseEvent has {button: 0, buttons: 0} or {button: 0, buttons: 1} inconsistently.

Specific Changes proposed

• Adds a case in utils/dom to consider (event.type === 'mousedown' && event.button === 0 && event.buttons === 0) a click.
• Removes a conflicting test. That is covered by the test above it for the mousemove event.

Fixes #8691, #7736

  • Change has been verified in an actual browser (Chrome, Firefox, IE)

Just wanted to note that on my laptop with 14.2.1 sonoma, I get button=0 and buttons=1. Going to update it and see if it changes.

Upgrading the macos didn't change the behavior. Setting up logging in the method, 95% of the time it does 0,1, but sometimes it is 0,0.
