Here's how "Ask Question" form looks like then:
You see, there's no toolbar, and no preview and no link to "upload image" control.
- I didn't even need MathJax to formulate the question - text with minimal Markdown would be enough for me
- some network resource becoming unreachable once in a while is just normal on the Internet - anything can happen in a distributed network.
The toolbar and preview should not break that harsh. They can degrade a bit, but they shouldn't break completely when MathJax fails to load.
