[BUG] Cannot create AKS on subnet with routetable in Azure portal

[JoeyC-Dev]

Describe the bug A clear and concise description of what the bug is. Optional: Set the appropriate GitHub label(s) to indicate the AKS feature or area you believe your bug relates to.

Azure portal has an over-strict check to prevent user from creating AKS when subnet is bound with routetable.

To Reproduce Steps to reproduce the behavior:

1. Create a subnet with routetable
2. Try to create AKS with BYO VNet, bound with that subnet

However, user does can create it via az-cli in the same subnet (no user-assigned managed identity required):

Expected behavior A clear and concise description of what you expected to happen.

Should be able to create AKS via Azure portal when subnet is bound with routetable.

Hi @tyler-lloyd, are you looking into this issue / do you have any updates you can share with the customer?

[tyler-lloyd]

I've notified the aks portal team and they are removing the validation that causes the option to be greyed out. let me see if I can get an ETA.
