I have noticed a change in the stackexchange mathjax typsetting viewer over the past few months:
The "preview" that is displayed when I real-time type my answer is not as attentive as it used to be: Sometimes I have to "post" my answer for it to be displayed with correct typesetting (so then I can make corrections as needed). This is annoying and it results in my (necessarily) posting a set of drafts of my answer, only for me to see the draft displayed correctly so that I can appropriately make changes. An obvious "fix" is to just wait for the system to correctly display my work in the preview mode...yet, lately, the preview seems to stall until I post.
Q: Is this just me and my computer, or is anyone else noticing this? Can anything be done?
I imagine that such posts-only-to-edit are confusing to readers who do not know these are only drafts. My current solution is just to make my fixes as quickly as possible to minimize the time my rough-drafts are displayed as answers.
[This is of course distinct from other situations where I post an answer that I think is good, only to notice typos/mistakes that I edit later. That situation is due to my own human-error, not the fault of the system.]
