The First meaningful paint metric seems to be incorrectly calculated on my Angular-Universal application. It seems to only consider the paint meaningful when some of the larger assets have loaded. However, as Angular-Universal renders the initial page in HTML first, and pushes the rest of the files later, this timing is quite inaccurate.

Am I doing something wrongly? Or is this expected behaviour?
