Using HTML tag for links before D2 code block breaks

[gnramos]

I am trying to link to specific parts of the text using HTML links (something like this). However, when I insert a div immediately before a D2 block, I get a strange behavior. If inline = true (in book.toml), it seems to generate the image (SVG inside the HTML) but it is not shown on the page. Otherwise it seems to work with mdbook build as expected but it starts looping and reprocessing the files if I'm using mdbook server.

Attached is a book with examples of this. mybook.zip

beats the hell out of me @gnramos!

i've tried diffing the html from chapters 1 and 2

diff book/chapter_1.html book/chapter_2.html                                                                                                                                                                                                                                   ✔  5s

there seems to be a few extra <p> tags thrown in there depending on whether or not you have that little snippet of text. No idea why.
