Support top level text nodes. #6
Description
The package currently does not work with top level text nodes.
A call to DomBuilder.text() throws when there was no call to DomBuilder.open() before that.
Unhandled exception:
Bad state: No element
#0 List.last (dart:core-patch/growable_array.dart:365:5)
#1 _DomBuilder.text (package:domino/src/markup_impl.dart:170:28)
It has the same error with the browser implementation.
