Description
Not global action preference variables are not strongly typed. As a result,
anything can be assigned to them, not necessarily valid values. For example,
typos will not be reported as errors, unlike with global variables.
In other words, PSSA should report issues like this, mind the typo:
$VerbosePreference = 'Cotninue'

Research direction
Start by tracing how PSScriptAnalyzer handles assignments to PowerShell action preference variables, then review the Local-ActionPreference example and the referenced behavior. Done means an invalid local value such as the misspelled 'Cotninue' is reported as an analyzer issue, while valid values remain accepted.
