#2388: Treat BaseComponent array appends as one. Fixes #2387.

Browse Source 
Don't copy formatting of previous element in the array being appended
but instead from the last appended component in the builder.
Otherwise formatting will be overridden in an incorrect way from
legacy text conversions.

Added unit test failed before this change. Now passes.
