Steps to reproduce the problem:
1. set CSS custom property with a custom string that is surrounded by single quotes, e.g., "--logo-path: '/20210629/asset/logo.svg';"
2. fetch the value via JS, e.g., getComputedStyle(document.body).getPropertyValue("--logo-path");

What is the expected behavior?
returned value is '/20210629/asset/logo.svg'.

What went wrong?
returned value is "/20210629/asset/logo.svg".

It is reproducible on Safari Technology Preview 184 as well and show 'double quotes' for single quote.

*** Safari Technology Preview 184 ***

naked:
/20210629/asset/logo.svg
double quotes:
"/20210629/s/assets/images/logo-alpine-group.svg"
single quotes:
"/20210629/s/assets/images/logo-alpine-group.svg"

*** Other Browsers (Chrome Canary 122 & Firefox Nightly 122) ***

naked:
/20210629/asset/logo.svg
double quotes:
"/20210629/s/assets/images/logo-alpine-group.svg"
single quotes:
'/20210629/s/assets/images/logo-alpine-group.svg'
