From the Compass Assistant bug bash https://docs.google.com/document/d/1s6fXOL00XXHw2C-ZI0kP8OW8fCtu28j2bdfe9QylE04/edit?tab=t.0

> Guide cue is cut off (I didn't open compass in full window; it was in the default size)

To get it to show again, in console do:

localStorage.compass_guide_cues = "[]"

and refresh.

Speaking to Sergey it sounds more like this guide cue might have survived by accident.

So the way to fix this is to set tooltipAlign to one of top, bottom, left or right. It defaults to bottom. Note that there's also tooltipJustify which we might also want to use. BUT this is the perf insight guidecue and perf insights can come from anywhere, so we don't know at that point which side is the best side. So it would have to be part of SignalPopover's interface so we can pass it down to guidecue].

And there are a bunch of places <SignalPopover> is used.
