Autocompletion gives no results for $PSItem / $_ in Catch blocks #7828
Description
Despite the fact that catch blocks should always receive an ErrorRecord object as the $_ or $PSItem value, there is no autocompletion / type inference performed for its properties, nor those of the Exception and/or InnerExceptions it contains.
Steps to reproduce
try {
throw "nope"
}
catch {
$PSItem.{tab}
}Expected behavior
$PSItem.CategoryInfo # And cycle through list of ErrorRecord properties on subsequent presses
(I know there's a programmatic way to get completion results, but I'm not familiar enough with how it works to be able to put that together at present.)
Actual behavior
$PSItem. # no completion results offered whatsoever
