Codeman maintainer d7f6047529 fix(tiles): a tile focus no longer leaves a glow listener on its tab
_selectTiledSession added a once animationend listener to the focused
tile's tab on every focus. On every skin but OG the glow is `animation:
none`, so animationend never fires: the listeners piled up on the tab (and
the class stayed). It now glows a tab only when it is not glowing already,
so a tab holds at most one; on OG the animation ends, the class goes and
the next focus glows again.

Measured (50 tile focus changes, daylight-blue): animationend listeners on
the tabs 0 -> 49 before, 0 -> 6 (one per tab) after. Over the leak run's
20 grid open/close cycles the page's listener count grew 1003 -> 1042;
this is the part CDP could attribute.

Live, this code: 50 tile focus changes leave 6 animationend listeners on
the tabs, one per tab.

The single view's copy of the same block (app.js selectSession) has the
same leak on every non-OG skin; it is a separate, pre-existing copy and is
left alone here.

Test: ten focus changes leave one listener; after animationend the next
focus glows again; mutation-checked.

Scope: PR 2 (tile-grid.js).
