Intellisense only works for the first parameter of an attribute #12771
Description
Steps to reproduce
Open up Powershell (with PSReadline), VS code (with Powershell extension) or even just the ISE and type in the following:
#2 suggestions pop up for the parameters "Options" and "ErrorMessage".
[ValidatePattern(<CTRL+Space>)]$StringToCheck
#No options show up
[ValidatePattern("\w",<CTRL+Space>)]$StringToCheck
#You can still tab complete the parameters.
[ValidatePattern("\w",O<Tab>)]$StringToCheckThis happens with any attribute.
Expected behavior
