Line break before img

Testing for wikimedia HTML rendering bug whereby:

(<math>1/r^2</math>)

can break the line between the opening bracket and the resulting image tag, also (rarer) between the image and the closing bracket. HTML output is

(<img class="mwe-math-fallback-image-inline tex" alt="1/r^2"
src="//upload.wikimedia.org/math/f/9/0/f905d700fc1410610c8b8fe7b5aaa859.png" />)

Test by changing font size (ctrl-plus / ctrl-minus) or by finely changing window width.

($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$) ($1/r^{2}$)

One solution that "seems to work" is to output <nobr>...</nobr> around the img tag and any text that abuts it on either side, but this is deprecated in current HTML and so may not be supported by all browsers.
