During review, the code for generating the resolution menu changed from

using a for [a, b] of scalingFactors.items() loop to a

scalingFactors.foreach((a, b)) call. However, the parameters for the

callback to Map.prototype.foreach are backwards compared to what is

returned by Map.prototype.items. This lead to the resolution menu

having its text and data-image-scale attribute swapped. This patch

addresses that issue.

Verified that the text and data attributes were generated correctly.
Verified that the menu switched the resolution.
