Wildcard dot where literal dot expected?

In cv.js both validationPattern have "(.[0-9]+)+" which afaik is intended to match dot separated numbers.

Unless JS regex is wildly different, this would normally be written "(.[0-9]+)+"

Just to confirm it's broken, see https://regex101.com/r/tbYsWN/1 where I can match a % instead of the . in one of the official spec examples:

There are 21 'full' base64 digits and the last one has at most 2 low bits set "[AQgw]". This is so that the base64 part fits in 128 bit value (216 + 12) = 128
The dot should be escaped (as mentioned above)
There is an optional '!' terminator

I believe the cV2 regex should be

new RegExp("^[" + base64CharSet + "]{21}[AQgw](\.[0-9]+)+!?$")

Validated this seems to work indeed:

First and last don't match, middle ones do:
