Unexpected space rendered

[matkoniecz]

I expected to see following question rendered as "← 'b'" but "← ' b'" appears (example reduced from problem appearing in a real set of questions).

[#1] ^^← 'b'^^
>>>a) filler
b) filler


<options> {
    "format": "2.1",
    "markdown": true,
    "mathjax": true,
    "explain": "always"
}

It seems that it's a MathJax issue. I have reported it. Hopefully it will be fixed in the next MathJax version.

Supposedly MathJax v3 improved rendering. Looking for volunteers to upgrade it :)
