Please update the tests to use the unprefixed version.

When unprefixing, you should also look into importing tests from W3C and the other vendors (blink and mozilla). We must make sure we have outstanding test coverage before unprefixing.

I ported few tests from W3C and Mozilla. I found the bug https://bugs.webkit.org/show_bug.cgi?id=138159 while trying to port one of the Mozilla tests.

The failure in LayoutTests/svg/custom/svg-fonts-in-html.html was happening because this test was using the un-prefixed 'columns' property.  The test was part of the patch which fixes https://bugs.webkit.org/show_bug.cgi?id=16980.  The intention for using the un-prefixed 'columns' property at the time, this test was added, can not be seen from the ChangeLog.  The 'columns' property has no effect since the test was added and it seems to be unrelated to the test.  The property seems to be left by mistake, maybe after realizing WebKit was not supporting the css multi column yet.  So I am fixing this failure by removing the un-prefixed 'columns' property.  By doing that we are going to get the layout of the page as it is used to be.

This is what I am doing.  The test I added (but changed its name to be fast/multicol/multicol-aliases.html) is about making sure the prefixed column properties are actually aliases to the un-prefixed ones.

Done. I added some test from W3C and mozilla.

Please make sure you have consistent indentation in the <style> content for the new tests (sometimes you have 2 spaces, other times 4). Similarly be consistent with having a space after the "property:". Lastly, sometimes your scripts use double quotes for strings - other times they use single quotes.

Same here.

And here.

I suggest just saying "Remove the use of the un-prefixed columns property since it seems unrelated to the test."

> LayoutTests/fast/multicol/column-box-alignment-rtl-expected.html:7
> +      margin: 0 0;

can just be "0"

> LayoutTests/fast/multicol/column-box-alignment-rtl-expected.html:21
> +      style="direction:rtl;
> +      text-align:right;"

You've copied the style attribute in.

Excellent. I'll land this manually right now.
