I think I see the problem here: after moving to a different workspace,
the window manager told Emacs that the frame was iconified (this is what
most window managers report to windows in a different desktop), and as a
result the icon and window manager names were changed to reflect
`icon-title-format'.

KWin seems to treat this as Emacs asking to be focused.

If you set `icon-title-format' to the same as `frame-title-format', and
in addition apply this patch:

diff --git a/src/xfns.c b/src/xfns.c
index 3a129211463..7f1128399a8 100644

-  if (EQ (name, f->title))
+  if (Fstring_equal (name, f->title))
     return;

does the problem go away?

Thanks.
