Created attachment 460672 [details]
the three file default all none

column-span have different display in chrome and webkit.
It might be a bug.
column-span default like all but must default none . default none is from https://developer.mozilla.org/en-US/docs/Web/CSS/column-span.
my webkit version is 2.36.0

The tests file do not contain anything useful and are not related to the title..

Thank you for filing this issue.

This looks to be about <details> in a multicolumn content. WebKit (historically) does not handle such content very well :(
