Building the find expressions for elements in HTML during recording respects the Identification Logic:

That isn't the case when Test Studio builds chained expressions though (e.g. it cannot find an Id or Name to build direct expression thus locates a unique parent element to include in the find logic.

In this case TS respects the Id or Name only and not the rest of the attributes (including custom ones).

It will be nice if the chained find expressions building algorithm is extended to respect the preset identification logic as well.
