As a user, when importing Robot Framework results I am able to see all levels of nested keywords

When importing Robot Framework results I should be able to see all levels of nested keywords.

Currently, only first level keywords are being displayed. For example, importing the following file

robot_report.xml

is currently generating the following results

and the inner keywords are missing.
