+Subject: [PATCH] fix(wlr/taskbar): do not bind to unsupported protocol
+ versions
+
+It's not allowed to bind to a higher version of a wayland protocol than
+supported by the client. Binding wlr-foreign-toplevel-manager-v1 v3 to
+a generated code for v2 causes errors in libwayland due to a missing
+handler for `zwlr_foreign_toplevel_handle_v1.parent` event.
