Yey! This is a fun one, I fixed it in Cliqz (a browser based on Firefox) a while ago: https://github.com/cliqz-oss/browser-f/pull/912#issue-195908...

If you are wondering why this discrepancy in behavior between platforms: This default behavior was initially changed to prevent a 16-years old bug in SeaMonkey, which was already fixed in Firefox since 2007. See following issues for more details:

* https://bugzilla.mozilla.org/show_bug.cgi?id=190615

* https://bugzilla.mozilla.org/show_bug.cgi?id=611162

Inertia I guess... happy to see this fixed upstream!
