We noticed that for MathJax only interaction it could cause issue as the `trimLeft/Right` function gets into infinite loop (wow!). This is a fix for that. We also ensure that the space around the text is displayed properly, that give some indication of selection.

Summary:
We noticed that for MathJax only interaction it could cause issue
as the
trimLeft/Rightfunction gets into infinite loop (wow!).This might be the contribution of some of the slowness issue we see.
This is a fix for that. We also ensure that the space around the
text is displayed properly, that give some indication of selection.
I also took a look at the upstream, but did not notice any relevant fixes
that is related.
Issue: https://khanacademy.atlassian.net/browse/DI-1513
Test plan:
Run
yarn startSelecting on the "Pure mathjax" interaction will show this issue without the fix.
