> (2) Prompt the testcase to draw a focus ring by pressing "Tab" after you load it

Note, I tried to automate the focus-ring action in this testcase, but that apparently doesn't work due to another bug with our image map handling. I filed bug 1878753 on that.

(With that fixed, we could create a better automated test for this sec issue here. In the meantime, an automated testcase here would probably need to use SpecialPowers or EventUtils or somesuch to synthesize a Tab keyboard-event.)

[EDIT Feb 8th: Looks like bug 1878753 is being fixed rather quickly, so we can morph this into a relatively-simple automated test, when we're ready to land tests here.  Hooray!]
