we already have 2 multisite listener with *.domain1.com with SSL wild card certificate, routing traffic to internal APIM.

now we have a requirement for adding another listener with *.domain2.com with wild card ssl cert *.domain2.com

while browing site1.domain2.com app gateway is presenting SSL cert from domain1.com and not from domain2.com as it is configured.
