Looking at the ezine seems likely to be a regression bug once validated...
 
 Fixed issue where under certain conditions smart tool was not able to slip edit clips with small fades. (CWBRN-5396, CWBRN-4157)
 Clip Lock icon obscuring the Clip name is no longer an issue. (CWBRN-23592)

During the first seconds you are clicking on the track, but not on the track number... From what I know, focusing track and selecting material are completely independent tasks.

You need to click the track number to select. There's a difference between track "focus" which is only on track at a time, and track selection, which can apply to multiple tracks.
 
SONAR has never selected clips based on track focus.

I'm selecting the way that I have always selected before and it has always worked before.

Just tried clicking on track number, no difference.

Clicking on the track number is absolutely imperative. Just clicking on the track brings the track "In Focus". Clicking on the number "Selects" the track (and the number on a selected track will turn blue). Only one track can be "In Focus" at one time but multiple tracks can be "Selected".
 
In Focus tracks can only perform some limited functions compared to fully "Selected" tracks.
 
If this is the confusion (which is understandable) then the test needs to be redone using the correct selection method.

Can we see a video of that approach. The previous video was helpful.

Are you holding the Ctrl key when selecting the 2nd track? That is how you multi select.
 

In case you missed my post, just tried clicking on track number to select, no difference.

Tested in X3, it does not work your way either (as expected).
 
BTW I am fighting with focus/selection/data cursor "triality" from other direction for quite some time already, I have not found the way to sync first two or first and third does not matter which tricks I have used... X2,X3,SPlat.
