Thanks for the explanation.

I expect broken html to not crash emacs though, and it does that in my
case. From its docstring, I understand that a high value of
max-specpdl-size could trigger such a crash, but that value doesn't seem
to be modified when entering the debugger. I have no idea where I should

(I guess it'd also be good if shr itself could cope with broken HTML
and/or have a friendlier error message, but that's less important)
