Brief Summary
As a horizontal tabs and non-Apple mouse user, I want the ability to scroll the horizontal overflow tab bar using my vertical mouse scrollwheel. I am aware shift + vertical scroll equals horizontal scroll in macOS but I want my vertical scroll movement to be translated into horizontal scroll while the cursor is on the tab bar.
Details:
This is the behaviour in Firefox and it makes navigating tabs a lot more frictionless.

I want the same behaviour in Orion. Without this feature, scrolling tabs is a pain because I am required to hold down the shift key.

I prefer showing website titles in tabs so my tabs overflow easily.

P.S. I made the same suggestion in https://orionfeedback.org/d/3526-allow-scrolling-through-horizontal-tabs-without-shift-key which was closed due to insufficient clarity. Please use this post instead.
