LGTM. Just a heads up, though, we probably shouldn't optimize too much for older browsers that we don't officially support. For example, looking at one of the error instances in Datadog shows a user using Chrome v87, when Open edX technically intends to support the latest 2 major versions; The edX.org support center article about browser versions denotes versions >100 of Chrome.

That said, given we already use _cloneDeep in at least one other spot, makes sense to utilize it as we're not installing any additional NPM packages in this change.

Related to browser support, you might also consider upgrading @edx/browserslist-config from pinned 1.1.1 to the latest version 1.4.0, which adopts the recommended "best practices" around browserslist usage. See https://github.com/openedx/browserslist-config/blob/42abbdb624ce64667a3246515d5cbc387dddc35f/index.js#L14-L20 for more details.

tl;dr; @edx/browserslist-config now also supports "last 2 versions and not dead" + "> 0.2% and not dead".

Here's a comparison of supported browser versions between these 2 releases of @edx/browserslist-config:
