[Bug] Formula rendering fails in answers and page freezes when typing `$`

[cicur]

I am using editor-formula with Apache Answer. I've encountered two issues:

1. Formulas are not rendered in the answer body, even though they work well in the question body and editor.

2. Typing $ symbols in the markdown editor causes the entire browser tab to become unresponsive.

Steps to Reproduce the Freezing:
Open any question/answer editor and type $ $$.

Environment:

• Apache Answer: 2.0.0
• editor-formula: 1.2.15
• Browser: Chrome 147 / Firefox 149
