Pagebreak beneath and section heading

[TomK32]

No idea wether this is mdpdf's doing or some other library used by mdpdf, but I stumbled across a page break right after the ## markdown section heading. This is a real document, luck would have it breaks at the markdown section.

First thing I tried is to apply a simple style:

h1, h2, h3, h4, h5, h6 {
  page-break-after: avoid;
}

Which worked as intended but of course now I have to copy over mdpdf's default.css and github-markdown-css.css to make the thing look pretty again.
Is there any chance of either adding the CSS that I provided above or adding a cmdline option like --append-style which just adds my css file rather than using it just exclusively.

Also, mdpdf won't accept multiple --style arguments. meow does have the isMultiple flag though for such cases.
