Elements don't resize well in Chrome

Known upstream issue: https://bugs.webkit.org/show_bug.cgi?id=87846

This is one of the biggest impediments to integrating the "fancystyle" branch (I can't use sizes for the pictureframe border that will reliably fit the viewport because borders don't support viewport percentage units, see https://bugs.webkit.org/show_bug.cgi?id=109229).

https://github.com/saabi/vminpoly could be used to work around this, but it still has a fair number of shortcomings that I don't feel like working on just to add eye candy.
