Handle view_count formatting on old browsers

## Issue
7102 Failed to initialize numberformat on some browsers

## Changes
Just revert to the non-SI notation (but still locale aware) for browsers that does not support the `compactDisplay` option.

I thought of adding an English-only abbreviation for that corner-case, but I think it's not worth the effort maintaining. There are worse issues happening on older browsers, such as icons not aligning properly in buttons and functions that require polyfilling.
