Only happens when the title would fit in a single line:

{title=$a_b$}
{height=400}
For long titles that go over a single line, it doesn't happen.
Removing from fixes for some reason, but breaks everything else, as it adds a global vertical scrollbar to the page if there are any images wider than it (when above the mobile mode where images are just width 100%.
ourbigbook.scss
:figure {
overflow-x: auto;
The fundamental issue seems to be: stackoverflow.com/questions/6421966/css-overflow-x-visible-and-overflow-y-hidden-causing-scrollbar-issue which we don't know how to work around. Omg.
To get a clearer effect edit ourbigbook.scss to:Only the separation between
.katex { font-size: 20.2em; }
a
and its subscript b
seems to matter.
