Spacing in matrix in `<me>` in feedback

[Chrissy Safranski]

I don't think this issue is related to the other spacing thread because it's very specific, but it does involve something being mysteriously pushed to the right, so who knows.  

Activity 2.6.2: What are triangular matrices?

If you try options A, B, or C to Task a, I put a matrix in `<me>` inside the feedback.  I saw that there was `<me>` in feedback in the sample book, so I wasn't expecting any trouble with this.  

But the right bracket of the matrix appears too far to the right. I tried with a matrix of all numbers and the same problem occurs, so it's not the asterisks.  It only seems to occur in `<me>` tags (not `<m>`) and only in feedback, not in a statement, solution, subsection text, etc.  

I upgraded to 2.30.2 to make sure that wasn't the issue, but the problem persisted.

Super weird to me, but in Task d, choice D I have a matrix in `<me>` in feedback where I've boxed some of the entries.  The right bracket on that matrix is fine.  

Both were constructed in the same way other than the boxed elements.  https://github.com/Tanaquil18/matrixcalculations/blob/main/source/sec-LUdecomposition.ptx The activity itself starts at line 78, and task d, option D's feedback starts at line 345.

Here is what I see:

Are you seeing something different?

If so, what browser are you using?

To see the weird spacing you need to pick a wrong answer and look at the feedback.

Thanks Sean - didn't read close enough.


Chrissy - 

It looks like you are making an extra column unintentionally.

The <me> samples have this:

.. \\ * \amp * \amp 0 \amp \\ ...

That has 3 separators and thus a 4th blank column.

The <m> samples do not.

Hah, well that will do it! Looks like only in 1 row, but that's enough. And I copy-pasted and modified, and so I continued to see it every time.

Thank you!
