mathjax2 render preview on top-left

[Q9-K]

I tried the mathjax2 demo and find that mathjax2 render the latex code a little slow, which causes if I close the plugin tip before mathjax2 completely render the latex code, then it will show the preview on top-left. In mathjax3 or katex, the engine's speed is enough that will not cause the problem.

The problem demo is on below:

Additionally, if i input long text and close the plugin tip after waiting the preview renders the code successfully, it will still cause the problem.
