In the following comment, both summands should appear before the period: A period appears in the middle of a formula The source for the comment is:

$\DeclareMathOperator\Hom{Hom}$Proof of the well known fact: $\Hom_H(V_H, V_H) = \Hom_G(V_H^G, V) = \Hom_G(V \oplus (V \otimes \epsilon), V) = 1 + [V \otimes \epsilon \cong V]$.

I've asked a related question before, but, in that case, it was able to be resolved by displaying the window full-size. That does not work in this case. (In fact, re-sizing the window doesn't seem to change anything; I always see the period immediately after the $1$.)

EDIT: The display above is what it looks like in desktop macOS Firefox. Desktop Safari gives me a different, but still wrong, line break: Differently bad line break on Safari It sure seems like the problems of overflowing math were fixed by giving each formula the maximum width that wouldn't overflow, and rendering it as a multi-line formula within that width if necessary—which is good!—but then the surrounding text needs also to be aware of this.

    $\begingroup$ I see that comment correctly, with the formula in one line and the dot at the end (and the line break before the formula). Which browser do you use? $\endgroup$

  • $\begingroup$ @StefanKohl, the first screenshot was from Firefox. I have now edited in what I see in Safari. Probably the conditions that trigger this bad breaking will be different depending on the particularities of the setups of different users, but I guess every user will probably see some variant of this some time. (It seems to be triggered when we would previously have seen overflowing math.) $\endgroup$

  • $\begingroup$ Is the way the comment is displayed different if you change the Math Renderer? This is what I see in Chrome with HTML-CSS: i.sstatic.net/xMla8.png $\endgroup$ Commented May 29, 2021 at 5:02
