investigate code coverage missing on complex lines of code

Overview:

when making function calls then assigning to a variable via await async function and see that there is no coverage (ts)

could not reproduce locally with javascript and complex function returns
debugged indicators function when applying coverage to more complex typescript await code. -
Saw the issue then which produced lcov lines that looked like they were missing entries for the function calls before the await.
most likely an istanbul issue or issue related to nyc setup locally (personal) after looking into the lcov.info file and seeing no coverage details for the lines in question (have to be covered as code directly afterwords is covered...)
