I compared this with the expand button with label in the language section. The actual result is consistent with selecting the text in other labels. I noticed one difference. The label has an actionable attribute which shows a pointer for the cursor. 

In most places in settings when selecting text in a label for a control, the control action is taken (links, toggles, and expansion).

Settings: cr-expand-button, use pointer cursor for label

The label when clicked toggles expansion. The bug as reported was
selecting the label text causes expansion. Without the pointer cursor
it's surprising to the user that an action will be taken while clicking
on the label text during selection. The problem is the surprising
expansion and not the expansion on clicking the text.

Update :
-------
Tested above issue in latest Canary build #70.0.3522.0 on Mac(10.12.6, 10.13.1 ,10.13.6, 10.14), Windows(7, 8, 8.1, 10) and Linux(14.04 LTS) OS and the issue is fixed. 
Now 'hand pointer' is seen when user is selecting the label text and the expansion action is taken (which is expected now due to the hand pointer). 
This behavior now matches with the behavior of most of places in setting page when selecting a label text.

This is working as intended as per the commit: https://chromium.googlesource.com/chromium/src.git/+/7d6f04d4a269351dcb2597a1712d100c001a3c28

Hence adding TE-Verified labels, kindly review an attached screen-cast for reference.

Thank you..!
