 In [changeset:"54100" 54100]:
 {{{
 #!CommitTicketReference repository="" revision="54100"
 KSES: Allow `min()`, `max()`, `minmax()`, and `clamp()` values to be used
 in inline CSS.

 Additionally, this commit updates `safecss_filter_attr()` to add support
 for nested `var()` functions, so that a fallback value can be another CSS
 variable.

 Follow-up to [50923].
