Explore binding between DOM elements in VS Code to the smoke test DOM element selectors

[michelkaporin]

Currently it is difficult to know if any of the DOM elements touched during a development work are used in the smoke test.

Continuation of #25291 (comment).

One example:
This following change lead to the smoke test failure because DOM element attribute was changed:
eac49a3
This attribute was used in the smoke test to grab the contents of SCM part in status bar:
0aec2d6

Exploration done and decision was made not to do any binding due to overhead and restrictions from the core code point of view.

Instead, log of smoke test failures should be created and maintained to understand common scenarios where tests fail because of loose binding or some other problems.
