[BUG] Math indented with a colon not rendering

[catsquawk]

Describe the bug

Math indented with a colon does not render, only the wikitext without the <math> tags is shown

To Reproduce

Navigate to the "Physics" section of https://en.wikipedia.org/wiki/Tide
(screenshot below)

The "Formation" section of
https://en.wikipedia.org/wiki/Ocean_gyre
has the same issue.

Expected behavior

The formula should be rendered correctly, as in the original Wikipedia page (screenshot below)

Screenshots

If applicable, add screenshots to help explain your problem.

Additional context

Relevant wikitext:

: <math>\text{tidal force} \propto \frac{M}{d^3} \propto \rho\left(\frac{r}{d}\right)^3,</math>

Another article that has math not indented with a colon looks fine in WikiReader.
https://en.wikipedia.org/wiki/Function_(mathematics)
(see "Dot Notation" under "Notation")

wikitext:

<math display="inline"> \int_a^{\, (\cdot)} f(u)\,du</math>

Hey, thanks for using this app. Sadly I am a bit busy with another app and I cannot maintain this app right now. I will get back to working on this soon. I hope you understand.
