+Subject: [PATCH] [options] Fix dict order py38 incompatibility
+
+python-3.8 dict changes introduce a traceback during our config file
+parsing for options with `-` characters in them.
+
+Fix this by changing an iteration of the dict keys from `dict.keys()`
+that returns a dict_keys view, to `list(dict)` which returns a list copy
+of the keys.
+
+Closes: #2206
+Resolves: #2207
