Comparison of LTR and RTL integrals.
Steps to reproduce:
Open the following example
<!DOCTYPE html>
<math displaystyle="true">
<msub>
<mo>∲</mo>
<mi>C</mi>
</msub>
</math>
<math dir="rtl" displaystyle="true">
<msub>
<mo>∲</mo>
<mi>ج</mi>
</msub>
</math>
Actual results:
When rendering an RTL stretchy character that goes into a position before the start, the clipping doesn't show the negative part.
Expected results:
The clipping should extend backwards and show the part above the subindex too.

:fredw, since you are the author of the regressor, bug 1789583, could you take a look?

The U+2232 ∲ was not mirorrable by default before bug 1789583, but the issue was already visible with other operators such as U+222B ∫. So I don't believe this the regression classification is correct here.

Jonathan, do you have an intuition for what might be going wrong here?
