i should be able to do it this week! |

this doesn't seem to affect fb too much (3 failing tests, but i'm not sure if they're caused by this) |
KaTeX prints a spurious error message during testing. This is ultimately due to a Jest configuration issue fixed in 21.0.0. References: * KaTeX issue: KaTeX/KaTeX#664 * Jest issue: jestjs/jest#3937 * Jest fix: jestjs/jest@fcf64d79a

Summary
As discussed in #3299, existing tests use an old-style HTML DOCTYPE, which makes it hard to test some modern web tools such as KaTeX; see KaTeX/KaTeX#664. This small tweak uses the recommended HTML5 DOCTYPE, which is probably a better default. Other issues such as #2460 could deal with the more general problem of making this configurable, but a reasonable default seems like a good start.
Test plan
We've tested over on the KaTeX side that it removes our warning about being in quirks mode. See KaTeX/KaTeX#747 (comment)
