/**
|
|
* This plugin computes the available width of converse-root, and adds classes
|
|
* and events so we can adapt the display of some elements to the current
|
|
* width/height.
|
|
* We can't rely on things such as @media, because in certain cases (for
|
|
* example when the chat is beside the video), the chat position and size
|
|
* depends on many other elements (video in large mode, ...).
