Payment buttons massively impact page speed

[Mingendahl]

Describe the bug If you activate the payment buttons (Apple- / Google-Pay), additional 33 (!!) requests to Stripe get fired in order to just create the payment button. This results in massive degradation of speed metrics (GTMetrix drop from A->B, Pingdom drop A->C, Pagespeed drop 77->39 ) which results in bad user experience and lower ranking in search results. On our pages, activating the payment buttons results in a 133% increase in total requests per page load.

To Reproduce Steps to reproduce the behavior:

1. Disable payment buttons
2. go to tools.pingdom.com and probe the page, check number of requests with stripe URLs
3. enable payment buttons
4. redo step 2 --> some 33 additional requests can be counted

Expected behavior Payment button integration uses a reasonable amount of requests (less than 5, best 1) and thus has no negative impact on speed metrics.

I can confirm this on my end as an issue as well, tested and confirmed with GTMetrix and Pingdom.
