Just looking at the stack here, I'm pretty sure what happens is that in nsDisplayBackgroundColor::BuildLayer we have:

  nsDisplayListBuilder::AddAnimationsAndTransitionsToLayer(
      layer, aBuilder, this, mFrame, GetType());

Where GetType() will return either TYPE_BACKGROUND_COLOR or TYPE_TABLE_BACKGROUND_COLOR.

In the test case, we are animating a table cell so I'm guess we hit the latter case.

When we get to LayerAnimationInfo::GetCSSPropertiesFor we have:

    switch (aDisplayItemType) {
      case DisplayItemType::TYPE_BACKGROUND_COLOR:
        return backgroundColorProperties;
      case DisplayItemType::TYPE_OPACITY:
        return opacityProperties;
      case DisplayItemType::TYPE_TRANSFORM:
        return transformProperties;
      default:
        MOZ_ASSERT_UNREACHABLE(
            "Should not be called for display item types "
            "that are not able to have animations on the "
            "compositor");
        return empty;
    }

I guess we should handle TYPE_TABLE_BACKGROUND_COLOR here.

[Boris Chiou [:boris]]

Attachment: Bug 1533968 - Don't add animations to layer for TYPE_TABLE_BACKRGOUND_COLOR.

nsDisplayTableBackgroundColor inherits from nsDisplayBackgroundColor, so
we should also handle its display item type properly when adding
transitions/animations to the compositor.
