@mmcky @jstac -- The following are mismatches between the HTML version and the PDF version of the textbook. I found relatively fewer issues in this chapter.
1. Algorithm line-numbering reset in Algorithm 6.1
The line numbering inside the nested block of Algorithm 6.1 resets to 1 in the HTML version. This appears to be the same algorithm line-numbering issue discussed in the Chapter 5 issue: #31.
I am noting this Chapter 6 instance briefly here so that it is clear that Algorithm 6.1 should also be checked once the fix is deployed.
Additional note on lowercase iid
I noticed a similar lowercase iid rendering in Chapter 6 as well, as shown below. This may be related to the \iidisim / myst.yml issue discussed in item 2 in the Chapter 5 issue: #31, so I am mentioning it here in case it is useful when checking the fix.
