Losing branch coverage in cobertura

[freemansoft]

I'm always getting zero branch coverage in my cobertura files

lcov.info for a file

and the cobertura for that file is

Just noticed that the lcov.info test input file in this repo doesn't have any brda entries.

Looks like branch coverage is imported when you have BRDA in the file but it is never output to the XML.

Maybe it wasn't picked up because the flutter BRDA records are trash.
