Martin Gräßlin 2a15592571 Simplify the window title passed in from the window system
Summary:
So far KWin used the window title provided from the window directly
without any sanitizing. This could result in broken window decorations
if the title included line breaks. Those were passed to the decoration
and depending on the way how the decoration renders the title, it could
result in visual breakage.

Having line breaks in a window title doesn't make sense. Given that KWin
now simplifies the title when copying it to it's own structure. This
also ensures that the title passed to e.g. task manager does not have
any line breaks on Wayland.

BUG: 323798
FIXED-IN: 5.8.4

Test Plan: Opened the web page in a nested KWin, properly rendered now.
