User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.103 Safari/537.36

Steps to reproduce:

Tried to print a SVG file with image positioned at x=0 y=0.
The margins on the Page Setup dialog box were at default values, all 12.7mm.


Actual results:

The SVG image was positioned right at the top and left edge of the page.
The header was printed on top of the topmost images.


Expected results:

The SVG image should have been placed with a margin of 12.7mm all around.

I thnk it's the result of one these bug reports:

Jonathan, any idea why the SVG style-sheet overrides the settings of the print setup?
Flags: needinfo?(jwatt)
I don't really know anything about printing, but it looks like nsPrintEngine::ReflowPrintObject does some styleSet stuff, and I guess that interacts badly with the nsDocumentViewer::CreateStyleSet changes in https://hg.mozilla.org/mozilla-central/rev/feff69cd698f
Flags: needinfo?(jwatt)
This seems to be due to SVG not getting the following style rules from ua.css:

*|*::-moz-page-sequence, *|*::-moz-scrolled-page-sequence {
  /* Collection of pages in print/print preview. Visual styles may only appear
   * in print preview. */
  display: block !important;
  background: linear-gradient(#606060, #8a8a8a) fixed;
  height: 100%;
}

*|*::-moz-page {
  /* Individual page in print/print preview. Visual styles may only appear
   * in print preview. */
  display: block !important;
  background: white;
  box-shadow: 5px 5px 8px #202020;
  margin: 0.125in 0.25in;
}

*|*::-moz-pagecontent {
  display: block !important;
  margin: auto;
}

*|*::-moz-pagebreak {
  display: block !important;
}

The easiest way to fix this would be to move this line to be after the if-else block:

https://hg.mozilla.org/mozilla-central/annotate/678cd6e8be91/layout/base/nsDocumentViewer.cpp#l2331

but that will regress SVG-as-an-image memory use and load time. Better would be to split up ua.css into SVG and non-SVG files in some way, but it's not clear what should apply in the SVG case. A fair bit of digging will be required to figure out which bits [can] apply to the anonymous frames that may be created above the nsSVGOuterSVGFrame.

I guess another way to fix this would be to use EnsureOnDemandBuiltInUASheet to load that sheet when we print, if there is an appropriate place to hook that into.

I talked with jwatt on IRC, I'll take this bug.

I think that it's better to add the code of loading ua.css when reflow of nsPrintEngine[1].

Oops, If we use the 'EnsureOnDemandBuiltInUASheet', Gecko will crash.
In this step, we don't call EndUpdate yet, thus I think that we should use 'PrependStyleSheet'.

Sorry I dropped the ball on this one. I meant to dig into whether there is a better way to do this, but apparently I'm never going to carve out the time to do that. For now, this seems sane.

Can you add a stack trace and description of what goes wrong (as best you can make out) to this bug to make sure this is documented for future bugzilla archeologists.

EnsureOnDemandBuildInUASheet() calls BeginUpdate()[1]. In nsPrintEngine::ReflowPrintObject, gecko create the style set which already opened.[2] So we don't need to create style set again.
