<!--
The sequences of white spaces following
the "A", the "GH", the "MNO" and the
"WXYZ" do not get collapsed. That is by
definition of 'white-space: pre-wrap'.
They 'hang': they behave like 'ink
overflow' while not contributing to
min-content sizing.
The line feeds (
) wrap
content to the next line box.
Since div#test-overlapped-red
is floated and since its parent in
the flow is 0-width, then the float
is min-content sized.
Since the widest line box
is created by the 4th line box
(due to "WXYZ" content), then
div#test-overlapped-red
must not be wider than 100px.
