Does <legend> element establish a new BFC? #2519
Description
In HTML5 spec said:
The `<fieldset>` element is expected to establish a new block formatting context.
What about the legend element?
Chrome and Safari will establish a BFC, see Blink code.
bool LayoutBox::AvoidsFloats() const {
// crbug.com/460704: This should be merged with createsNewFormattingContext().
return ShouldBeConsideredAsReplaced() || HasOverflowClip() || IsHR() ||
IsLegend() || IsWritingModeRoot() || IsFlexItemIncludingDeprecated() ||
Style()->GetColumnSpan() == kColumnSpanAll ||
Style()->ContainsPaint() || Style()->ContainsLayout() ||
Style()->Display() == EDisplay::kFlowRoot;
}
I think the specification should be clear, to avoid incompatibility between browsers.
