+# The previous floating dependency had resolved to a January build whose vendored
+# pop-os/iced predated 686c6afb8 ("fix(sctk): popup initial configure ack
+# handling"). Without that fix, creating a popup or tooltip surface could attach a
+# buffer before acknowledging the initial configure, and the compositor killed the
+# applet -- libcosmic#1166.
+#
+# An older revision that merely contains the fix is not practical: libcosmic
+# declares several dependencies (cosmic-text, iced's own tree) as floating git
+# deps with no revision, so an old libcosmic resolves against today's versions of
+# them and fails to compile. There is no committed Cargo.lock in libcosmic to
+# reconstruct a contemporaneous graph from, so tracking a recent revision is the
+# maintainable option.
