Is anyone aware how can this be fixed (by, say, forcing MathJax to create a new line) automatically?

This bug is years old. It was first reported on the main Meta site, after which a bug report was made in MathJax. Unfortunately, the bug report is still open. There's not much that can be done about it.
It seems that replacing $\begin{align}
with $$\begin{align}
- and adding a dollar sign at the end as well - adds a horizontal scrollbar. That means that the user needs to scroll a bit, but that seems a better option than overflowing into text for formulas that don't fit (without correct flow control). Obviously a better flow control would be the final solution, but this seems to be a good workaround. This workaround should be preferred to letting the text overflow, as that may well produce unreadable results. Comment here if the workaround does not work for you, and please include browser and environment information if you do.
Unfortunately, like many sites, SE doesn't allow full width browsing, so we will always be a bit space-limited until we at least get an option to enable it.
In the mean time, I've added the first thumbs up to the initial bug report on GitHub, please add your "votes" if you agree with it. This is not something SE is likely to be able to fix on their own after all.
