[Docs] Infinite network requests loop in Safari and iOS

Created by: dcastil

Describe the bug

When I try to access https://create-react-app.dev with Safari, the browser gets stuck in an infinite loop, trying to load following SVG:

data:image/svg+xml;utf8,<svg fill="currentColor" alt="Search" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 16 16" height="16px" width="16px"><path d="M6.02945,10.20327a4.17382,4.17382,0,1,1,4.17382-4.17382A4.15609,4.15609,0,0,1,6.02945,10.20327Zm9.69195,4.2199L10.8989,9.59979A5.88021,5.88021,0,0,0,12.058,6.02856,6.00467,6.00467,0,1,0,9.59979,10.8989l4.82338,4.82338a.89729.89729,0,0,0,1.29912,0,.89749.89749,0,0,0-.00087-1.29909Z" /></svg>

The computer runs pretty hot just after a few seconds.
