1Password + Tampermonkey breaks Google in Safari on Sonoma
This problem started today (8/19/2023) after both 1Password for Safari and Tampermonkey updated their shell apps. I can't point a finger at either app specifically since they both work fine without the other. Both apps are at their current release versions as of today.
The problem is that in Google search result pages, left clicks on search result headings no longer take the browser to those pages. Right clicking and Open in New Tab still works fine, as does Command-clicking.
The problem is 100% consistent and reproducible, but to reproduce, both the 1Password and Tampermonkey extensions must be enabled in Safari.
It is NOT necessary to reload the Google results page after enabling or disabling either extension - the issue seems to relate to the click processing and not the actual page HTML.
It is NOT necessary that any actual Tampermonkey script be running on the Google results page. Just the fact that Tampermonkey is enabled is sufficient to trigger the bug.
Note that Sonoma is a beta version of macOS. I do not know if the problem occurs under the released version of macOS.
Tampermonkey app version is 4.20.6184, downloaded from the Mac App Store.
