1869532 - Recalculate virtual-list maxRenderCountEstimate on window resize in Firefox View

Status: RESOLVED FIXED

(Firefox :: Firefox View, task)

Description

[Kelly Cochrane [:kcochrane]]

Since we use window.innerHeight to determine how many items to render at one time in the virtual-list, we'll need to make sure that value is updated when the window is resized. We should handle this in viewpage.mjs to ensure we're only adding one event listener on the window at one time. We should also use DeferredTask to make sure we're debouncing.

We should land this as a follow-up to bug 1857634, so that we can reference this new updatesPaused property in fxview-tab-list when deciding which virtual-list elements to recalculate values for one window resize.
