     [15.02.2024] pzotov
     Checked on 4.0.5.3059 (commit #a552f1f3), 5.0.1.1340 (commit #f7171b58).
     NOTE: 3.0.123.3731 (dob=15.02.2024) does NOT pass this test.

+    [16.02.2024] pzotov
+    Added [temporary] mark for SKIP this test when QA runs agains *fork* of standard FB because it hangs ('disabled_in_forks').
+    This mark will be removed after separating QA runs (executing tests against standard FB snapshot on DEDICATED machine).
+
+    NB-1. QA must use command like: 'pytest -m "not disabled_in_hqbird" ...' when check *fork* of standard FB.
+    NB-2. Unfortunately, nowadays QA runs for standard FB and its fork are performed at the same host.
+          Lagging problem exists with [back-]porting of some fixes/features into fork after implementation for the same FB-major version.
+          This can cause the whole QA-job to be incompleted and missed report for one of even several days.
