-ScriptArgs not working with "=" in other arguments

I am using the following arguments in PowerShell with the bootstrapper:
`.\build.ps1 -target=build -configuration=Debug -ScriptArgs='--packageVersion="1.0.0-dev"'`

### What You Are Seeing?
`packageVersion` is staying set to the default value, "1.0.0".

### What is Expected?
`packageVersion` = "1.0.0-dev"

When I remove '=' from arguments, I get the expected results:
`.\build.ps1 -target build -configuration Debug -ScriptArgs '--packageVersion="1.0.0-dev"'`

### What version of Cake are you using?
v0.32.1

### Are you running on a 32 or 64 bit system?
64-bit

### What environment are you running on? Windows? Linux? Mac?
Windows 10

### Are you running on a CI Server? If so, which one?
TeamCity

### How Did You Get This To Happen? (Steps to Reproduce)
