Description

<partial name="view" view-data-additionalItem="abc" />

The IDictionary<string,object> has a very helpful way to add item , But this line of code throw exception because view-data is null .

I suggestion to either support this razor syntax or add a new attribute to add addiontal item to the partial view and not effect the current view‘s ViewData

Contributor guide

Research direction
Examine the Partial Tag Helper implementation to understand how view data attributes are processed and why `view data` is null when using the hyphenated syntax.
