Get-EC2Subnet filter does not honour wildcards like '*' and '?'

[siriuschan9]

Describe the bug

Cmdlet: Get-EC2Subnet
Parameter: -Filter

When the Name property of the -Filter parameter is 'subnet-id', the filtering behaviour does not honour wildcards like '*' and '?'.

For example:

Get-EC2Subnet -Filter @{Name = 'subnet-id'; Values = '*'}

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

I expect the command in the example to return all Subnets.

Current Behavior

Nothing is returned.

Reproduction Steps

Get-EC2Subnet -Filter @{Name = 'subnet-id'; Values = '*'}

Possible Solution

No response

Additional Information/Context

This command will return all VPC.
Get-EC2Vpc -Filter @{Name = 'vpc-id'; Values = '*'}

This command will return all Internet Gateways.
Get-EC2InternetGateway -Filter @{Name = 'internet-gateway-id'; Values = '*'}

But - this command returns nothing.
Get-EC2Subnet -Filter @{Name = 'subnet-id'; Values = '*'}

This seems to be a limitation of the DescribeSubnets API, even the CLI command (aws ec2 describe-subnets --filters "Name=subnet-id,Values=*") returns empty results.
