1441017 - Arrow panels should have no padding and hidden overflow by default

Status: NEW

(Toolkit :: UI Widgets, enhancement, P5)

Description

[:Paolo Amadini]

We have many rules to override the default padding and overflow mode of arrow panels:

.browser-extension-panel > .panel-arrowcontainer > .panel-arrowcontent {
  padding: 0;
  overflow: hidden;
}

Making this the default for arrow panels will allow the rules to be simplified, and the "photon" attribute to be removed from some of the panels.

Individual views may use --arrowpanel-padding to determine the platform-specific padding to use, however it is not clear if this is actually applied anywhere other than browser notification panels. We can consider using the same padding in the notifications as the identity block and other panels.
