    <thetext>The following tests regressed, per bisection, in 273742@main...273733@main. Given they&apos;re all visibility interpolation, I presume 273742@main.

    <thetext>Huh, yeah. Not sure what went wrong there, this shouldn&apos;t have been found it was already fixed on ToT. (i.e., it should&apos;ve just short-circuited and quit!)
