bug#45520: 28.0.50; mode-line-compact doesn't do text properties

[Lars Ingebrigtsen]

I thought the issue was with `format-mode-line', but that function does
return text properties as ordered (I think).  Instead the issue is that
display_string doesn't do anything with the text properties?

If this can't be fixed somewhat easily, I guess I'll revert the
mode-line-compact change, because it's pretty useless without text
properties, but I don't have the time right now to investigate, so I'm
reporting this as a bug to remind myself (or anybody else who feels like
having a look).
