bug#65896: 30.0.50; folding text with text properties prevents background from extending past the newline

[StrawberryTea]

What I’m saying is that, I start up GDB and I set a breakpoint on Frecenter and
step into display_line, I can see the glyph row and how all the characters in
the folded heading have the heading except the newline character at the end. And
I would like for in this specific scenario, the face on the ellipsis to be used
(since it has extend) instead of the face on the newline which is the default
face. But I don’t know how to make that modification to the code yet.
