Description of change
Since merging #2824 into master, Travis reported some test failures in the sortable bid adapter for certain browsers. See link below for errors:
https://travis-ci.org/prebid/Prebid.js/builds/402733184
After investigating, it was determined to be caused by the usage of
Number.isInteger()
in thesortableBidAdapter
file. This PR swaps out the reference for theutils.isNumber()
function which has the proper polyfills for the needed browsers.
