<embed style="border: 2px solid red; outline: 4px solid blue;"> The blue border does not display. This seems to be because RenderEmbeddedObject::paint() doesn't use the same pattern as RenderBlock etc: bool pushedClip = pushContentsClip(paintInfo, tx, ty); paintObject(paintInfo, tx, ty); if (pushedClip) popContentsClip(paintInfo, phase, tx, ty); where popContentsClip paint the outline.
Hi, If no one is working on this, i think i can work on it.
Please do. Assign the bug to yourself if you wish to work on it.
@Simon - I think this outline issue for <embed> tag has been resolved. I verified on chromium (linux) Webkit Gtk Port.
Would be nice to know which commit fixed it.
yes, I will dig to find out.
I am digging to find out the exact revision. Given below is the stack which paints the outline. 0 WebCore::RenderObject::paintOutline RenderObject.cpp 1121 0xb57147e2 1 WebCore::RenderWidget::paint RenderWidget.cpp 255 0xb576d8b4 2 WebCore::RenderEmbeddedObject::paint RenderEmbeddedObject.cpp 147 0xb56bd8e3 3 WebCore::InlineBox::paint InlineBox.cpp 240 0xb56208dc 4 WebCore::InlineFlowBox::paint InlineFlowBox.cpp 1069 0xb56251e2 5 WebCore::RootInlineBox::paint RootInlineBox.cpp 196 0xb577316d 6 WebCore::RenderLineBoxList::paint RenderLineBoxList.cpp 262 0xb56fe1c0 7 WebCore::RenderBlock::paintContents RenderBlock.cpp 2580 0xb5642330 8 WebCore::RenderBlock::paintObject RenderBlock.cpp 2690 0xb5642a90 9 WebCore::RenderBlock::paint RenderBlock.cpp 2435 0xb5641622 10 WebCore::RenderBlock::paintChildren RenderBlock.cpp 2624 0xb564260b 11 WebCore::RenderBlock::paintContents RenderBlock.cpp 2582 0xb564234b 12 WebCore::RenderBlock::paintObject RenderBlock.cpp 2690 0xb5642a90 13 WebCore::RenderBlock::paint RenderBlock.cpp 2435 0xb5641622 14 WebCore::RenderLayer::paintLayerContents RenderLayer.cpp 2912 0xb56f0e90 15 WebCore::RenderLayer::paintLayerContentsAndReflection RenderLayer.cpp 2813 0xb56f08ef 16 WebCore::RenderLayer::paintLayer RenderLayer.cpp 2794 0xb56f07ee 17 WebCore::RenderLayer::paintList RenderLayer.cpp 2977 0xb56f132b 18 WebCore::RenderLayer::paintLayerContents RenderLayer.cpp 2933 0xb56f107f 19 WebCore::RenderLayer::paintLayerContentsAndReflection RenderLayer.cpp 2813 0xb56f08ef 20 WebCore::RenderLayer::paintLayer RenderLayer.cpp 2794 0xb56f07ee
I slightly changed the test case as below from Comment 0: Link - https://jsfiddle.net/xw9zb8vu/show Only Firefox Nightly 104 is drawing the blue border with red inside, while Safari 15.6 and Chrome Canary 106 does not draw anything. I am not sure on whether there is any plan for <embed> to support or enhance this further, so I will leave it up to the team but just wanted to share updated testing result. Thanks!
