fitBound end up in error of NaN after call

mapbox-gl-js version: 1.13.1

browser: Tested in Chrome and Firefox

Steps to Trigger Behavior

1. Set a map element with a size x (example: 400px)
2. Call fitBounds method passing CameraOptions with padding being x / 2 (example: 200px)

Expected Behavior

Map should fit to provided boundaries

Actual Behavior

At this moment when it happens to map element width to be x and the padding (right and left) to be x / 2 we end up with the Point object generated in _cameraForBoxAndBearing to be a set of NaN of x and y, this happens due to the fact we multiply 0 with Infinity and the method just throw an error.

• https://github.com/mapbox/mapbox-gl-js/blob/main/src/ui/camera.js#L579
  Here we have scaleX being assigned to 0 as tr.width being x (e.g: 400px) and edgePadding.left or .right being 0 and eOptions.padding.left or right being x / 2 (e.g: 200px)

• https://github.com/mapbox/mapbox-gl-js/blob/main/src/ui/camera.js#L588
  zoom is assigned to -Infinity as in tr. scaleZoom it does Math.log(scale) / Math.LN2 and log of 0 if -Infinity

• https://github.com/mapbox/mapbox-gl-js/blob/main/src/ui/camera.js#L597
  offsetAtFinalZoom is assigned to { x: NaN, y: NaN } as we have tr.zoomScale(zoom) returning 0 as result to Math.pow(2, -Infinity) and we get y/0 which turns into Infinity and finally we get .mult returning NaN from 0 * Infinity

Start in src/ui/camera.js at _cameraForBoxAndBearing, following the fitBounds path and the scale, zoom, and offsetAtFinalZoom calculations described in the report. Reproduce the case with a 400px map and 200px left and right padding; done means fitBounds no longer produces NaN coordinates or throws when the available width is zero.
