feat(core): add host node to DeferBlockData
Add the host/container comment node to the
DeferBlockData. This node can be used as a@deferblock locator, in the DOM tree, in the absence of root nodes.fix(devtools): support for @defer-only blocks; defer declared blocks
With the help of the above-mentioned commit (i.e. the host node), we can now locate and render in the component tree the
@deferblocks that don't have a placeholder. Additionally, the commit fixes a couple of minor bugs related to showing@placeholderand@loadingblocks pills in the details panel even if they are not declared.
