Some float images that display fine in HTML are not being included in rendered WeasyPrint PDFs using 0.42+.

Reproduce

A very simple self-contained html document which has a couple images. This is a simplified version using actual CSS from Bootstrap (which is what my actual site is using):

<html>
<body>
<img src="https://i.imgur.com/mK3ufI3.png">
<div style="float: right;"><img style="max-width: 100%;" src="https://i.imgur.com/mK3ufI3.png"></div>
</body>
</html>

The output looks like this (or live https://jsfiddle.net/kzLhtejh/):
image

When generating a PDF from this HTML with WeasyPrint 0.41, the render looks correct:

$ pip install WeasyPrint==0.41
Collecting WeasyPrint==0.41
  Using cached WeasyPrint-0.41-py3-none-any.whl
...
Installing collected packages: WeasyPrint
Successfully installed WeasyPrint-0.41

$ python -c "from weasyprint import HTML; HTML('pdf.html').write_pdf('test.pdf')"
$

PDF render:
image

However when simply upgrading to WeasyPrint 0.42, the PDF render is missing the floated image:

$ pip install WeasyPrint==0.42
Collecting WeasyPrint==0.42
  Using cached WeasyPrint-0.42-py3-none-any.whl
...
Installing collected packages: WeasyPrint
  Found existing installation: WeasyPrint 0.41
    Uninstalling WeasyPrint-0.41:
      Successfully uninstalled WeasyPrint-0.41
Successfully installed WeasyPrint-0.42

$ python -c "from weasyprint import HTML; HTML('pdf.html').write_pdf('test.pdf')"
$

PDF render:
image

All subsequent versions of weasyprint have the same result. Here is a comparison of the two versions, there were quite a few changes to float logic - v0.41...v0.42

I did notice #561, however cairo versions do not have an affect, it's purely in WeasyPrint.

A little more research...

Commit 1076b10 seems to have broken this.

If I reset the repo to this commit and install it:

$ git reset --hard 1076b106ea212c3ddc15730a6efda30f16c527e9
HEAD is now at 1076b106 Ignore intrinsic size for replaced boxes with percentage-based width

$ pip install -e .
Obtaining file:///Users/vagrant/jesse/WeasyPrint
...
Installing collected packages: WeasyPrint
  Running setup.py develop for WeasyPrint
Successfully installed WeasyPrint-0.41

The generated PDF is still broken. If I revert this commit:

$ git reset --hard HEAD~1
HEAD is now at a317b636 Fix typo

The generated PDF is correct.

Note that 1076b10 says it was implemented to fix #227.
