Unable to render sentence when formula is at the start of it

[chloe-tan]

When a formula is at the very start of a new line,

• E.g. $$ W_A\Delta_B$$ test hello world.
• Renders only the formula, all remaining text is gone:

But if we add some extra text at the start of the sentence, everything works fine

• E.g. a $$ W_A\Delta_B$$ test hello world.
• Everything renders as expected
