It looks like the current behaviour was deliberate, but I don't know why it was done the way it was.I do not remember either. One possibility could be that the resulting HTML is not valid, like no <img> in <pre>, but I do not have checked if it is so.
<img> is valid in <pre> in HTML5, by my reading:
https://www.w3.org/TR/html5/grouping-content.html#the-pre-element
https://www.w3.org/TR/html5/dom.html#phrasing-content-1
It is not valid in HTML4.
https://www.w3.org/TR/html4/struct/text.html#edef-PRE
The fix: makeinfo should stop emitting:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd";>
Instead we should follow the HTML5 recommendation and emit:
<!DOCTYPE html>
This only effects validation, I believe.
Older browser should have no problems, except the shortened DOCTYPE
should be present to disable quirks mode.
