Hey friends who work at Google,
I've already submitted this as "feedback", but since I have no way to know if anyone is actually reading that (why doesn't it give you a bug # or something so you can follow up?).... I'm hoping that you can get this noticed by someone on the correct team so I can continue to using Google Docs to write latex. (Which is awesome for collaboration BTW...)
It appears that after there have been 100 actual misspellings in a document, google docs starts marking words over 12 characters long as incorrect, even if they are spelled correctly. This does not appear to affect shorter words. Also, you can temporarily fix it by retyping the word, but the issue returns upon refreshing the page.
Thanks to +Andy Konwinski
and +Beth Trushkowsky
for procrastinating the morning away helping me narrow down the issue!
