1912008 - Add a new API to support better control over viewport resizes

Status: NEW

(GeckoView :: General, enhancement)

Description

[Petru-Mugurel Lingurar [:petru]]

Based on the discussions and recommendations from https://bugzilla.mozilla.org/show_bug.cgi?id=1908249#c12 GeckoView needs to expose a new API

• which doesn't change the layout viewport in the case of interactive-width:resizes-visual or interactive-widget-overlays-content but
• does change the layout viewport in the case of interactive-widget=resizes-content

to supplement setDynamicToolbarMaxHeight and setVerticalClipping.

This is useful in the case when the dynamic toolbar height changes while in a webpage (see bug 1908249 for such a scenario).
