v7 fails to find the tests when sub-suites are used

[realtimeprojects]

Given the following directory layout

tests/
   suite1/
       suite11/
           test1.robot
           test2.robot
   suite2/
       test3.robot

When running the following command line:

robot ... --suite suite1 tests/

robot successfully finds and executes test1 and test2, however, when using:

robot ... --suite suite1.suite11 tests/

will fail to find the tests and produce an output

Suite 'Tests' contains no tests or tasks matching tag... in suite 'suite1.suite11'.

The following commands, however, will successfully find and run the tests:

robot ... --suite tests.suite1.suite11 tests/
robot ... --suite *.suite1.suite11 tests/

This misbehavour was introduced with Robot Framework 7.0 (Python 3.11.2 on linux) of robot framework. Using robot Robot Framework 6.1.1 (Python 3.11.2 on linux) the command above works fine.

This behavior was changed to make --suite and -test behave consistently. For details see #4720.
