@Mithoron indeed, I am not too keen on reading the whole long thing :(

$\ce{\bond{3}}$ $\ce{\equiv}$

@mhchem okay this is now interesting: the bonds look different in the Chatroom and on the SE site :O (in the chatroom, I use ChatJax++ userscript)

@GaurangTandon Could you try a plain $\equiv$ ($\equiv$) without \ce?

I don't know what version of mhchem ChatJax++ loads. In fact, I cannot find mhchem anywhere in the code.

@mhchem tried again, still exactly the same output

@GaurangTandon Yes, I can reproduce it here, in Chrome. It does not happen on high-res monitors. So time is playing for us. :-) But because mhchem just re-used the standard \equiv, I see the issue with the MathJax guys. They are currently discussion to switch to another font with MathJax v3, so I'd say a bug report does not make too much sense, at the current time.

@mhchem Nice digging, and thanks for the helpful info ^_^

Anyone has any clues on what we should do here? Perhaps, post a new question to cover some problem specifically? (cc @Martin-マーチン)

I would argue that anyone who finds this page has a well enough chance of finding the other question, hence the question has actual purpose. On the other hand, the question itself is mixing definitions and making assumptions beyond the useful; it would be incredibly hard to focus whatever is left into something more useful.

@Martin-マーチン okay, np
