In [this post](https://math.stackexchange.com/a/583044/35416) I pasted some R code:

```
> r <- eigen(A)
> V <- r$vectors
> lam <- r$values
> Lmbd <- diag(lam)

```

This was entered as

![entry form](https://i.stack.imgur.com/aPSnc.png)

but at the time of this writing gets rendered as

![rendering](https://i.stack.imgur.com/8HpIQ.png)

The third line was indented no more than the others, but it gets rendered with four space indentation which the other lines don't have, both in the preview and the saved version.

Could this be some aspect of math rendering involved here, something confused by the dollar signs in there?
