Bug 266880 – Make "Outdent" command to respect CSS display property

• Component: HTML Editing
• Status: RESOLVED DUPLICATE

[Ahmad Saleem]

Hi Team,

While going through Blink's commit, I came across following commit, which I think can be merged:

Blink Commit: https://chromium.googlesource.com/chromium/src.git/+/73a2d635d5779e1092de3d26e4ee33d758d46444

WebKit Commit: https://github.com/WebKit/WebKit/blob/b2da34277e48164f292542ed493e1c4177fba7ce/Source/WebCore/editing/IndentOutdentCommand.cpp#L47

Below compiles and don't regress anything in 'WPT' (selection / editing etc.):

// Returns true if `node` is UL, OL, or BLOCKQUOTE with "display:block".
// "Outdent" command considers <BLOCKQUOTE style="display:inline"> makes
// indentation.
static bool isListOrIndentBlockquote(const Node& node)
{
    const auto& element = dynamicDowncast<HTMLElement>(node);
    if (!element)
        return false;
    if (!node.renderer() || !node.renderer()->isRenderBlock())
        return false;
    return node.hasTagName(ulTag) || node.hasTagName(olTag) || node.hasTagName(blockquoteTag);
}

Just wanted to raise to get input, if we can fix it.

Thanks!

It could be potential optimization as well to early return if it is not 'HTML' document and also if it does not have any renderer.
