1619214 - Use parentFront property in Pool.js

Status: RESOLVED FIXED

(DevTools :: Framework, task, P3)

Description

[Nicolas Chevobbe [:nchevobbe]]

In Pool, there are 2 places where we use poolFor in order to retrieve the parent. Depending of the number of pools and their sizes, this could be quite costly.

In many fronts, there's a parentFront property that maintain the link between a front and its parent.

The idea would be to use this if it exists, and fail back to poolFor only when needed, as it could be much more efficient.

In many fronts, there's a parentFront property that maintain the link between
a front and its parent, but Pool isn't using it, and retrieve the parent
through poolFor, which can be a bit slow depending the number of pools and
their size.
Trying to access the parent through parentFront if possible should be more
efficient.
