Why do you need to select only .avatar class children?

[dpapad, 2017/06/22 23:22:48]

At cr_profile_avatar_selector.html the only thing passed to the grid looks as
follows:
<paper-button class="avatar">...</paper-button>

Given that now there is a call to querySelectorAll() in
cr_profile_avatar_selector_grid.js, I figured that using the 'avatar' class
instead of 'paper-button' was better since paper-button is just an
implementation detail, whereas 'avatar' has some semantic meaning.

I can revert this and change the selector to querySelectorAll('paper-button') if
you think is better.

No that's good. I just was curious as to reasoning.
