 EWW: Loses on some content on Wikipedia (especially science/math)

Compare the rendering of this page
https://en.wikipedia.org/wiki/Gamma_function

in eww vs  the now ancient W3. I still get more content from W3 than I
do with EWW -- likely because I get all of the alt text fo rthe math
equations which Wikipedia helpfully gives me as LaTeX.

Hm.  If I look at the page in eww and in Firefox, they seem to contain
just about the same data (with different layout).  And all the equations
seem to have the LaTeX-like stuff as alt texts in eww, too, like:

\Gamma(t) = \int_0^\infty x^{t-1} e^{-x}\,dx

Hmm

When I rendered the page in EWW, (with images turned off) the entire alt
text was not present in the rendered buffer -- I could see the alt text
by pressing "a" 

As an example, in my Emacs (running under X/StumpWM)


alt=
\Gamma(n) = (n-1)!
 
In-buffer presentation:

\Gamma(n
 .

Aha.  Is this with `shr-blocked-images' set to something that blocks all
images?  Yes, in that case I can reproduce this error -- it only shows
ten characters of the alt text instead of the entire string.

I'll fix the bug.

Correct -- I set up shr to not load or show images :-)
