Hi!

I noticed that the time to create the layout of a page grows with the amount of pages that were processed already. I've been experimenting with a rather large document and this increase can make a whole build take a really long time.

Perhaps this is something that has to do with my input document? Are there any general tips on how the input document/css rules should be structured in order to reduce this growth?

Mine looks like this:

body
    section.cover
    section.toc
    section
        h1
        section
            h2
            [content...]
        section
            h2
            [content...]
        ...
    ...

[content...] being paragraphs and divs (with KaTeX rendered math)

As a side note, I've ran a profiling session with the Chrome dev tools. It turns out that commenting out this line really helps bringing down the increase, enough so to reduce my 2hours+ build to ~25min. Indeed the modification of the pages root element's style appears to cause a "restyle" browser task for the whole document, for each page added. That restyle happens when this line is executed. I am unsure of the use of this variable (I've found it there only), I could not find any visual change on my document after disabling it. Is it safe to do so?

Thanks for your time on this project, by the way!
