Header value character limit in Azure Front Door rules engine
I'm trying to use the new rules engine configuration in Front Door to append a Content-Security-Policy header to a static website hosted in Azure Storage. Currently there is a limit of 128 characters for the "Header value", a limit you reach quickly if you have a couple of external scripts/style/image/etc sources.
The character limit needs to be significantly increased to support anything other than the most basic CSPs.
This disqualifies Front Door as an option for us.

Facebook has a CSP header of 634 characters, Twitter has 2212 characters. 128 characters is ridiculously low.
