multiple letter deletion: "text-change" source type is "api" instead of "user"

[sagacitysite]

When I mark some text (multiple letters) and press delete key on my keyborad, the "text-change" event is fired as expected. But: The source is of type "api", but it should be of type "user" (if I'm right in understanding the distinction ;)

Expected behavior:
source type of text deletion (multiple letters) should be "user"

Actual behavior:
source type of text deletion (multiple letters) is "api"
