Function When_I_find_closest_element

When_I_find_closest_element(selector: string): void
When I find closest element:
```
When I find closest element {string}
```
Get the first DOM element that matches the selector (whether it be itself or one of its ancestors).

The querying behavior matches exactly how .closest() works in jQuery.
Parameters
- selector: string
Returns void
Example
Find the closest element with the class banner:
```
When I find closest element ".banner"
```
Remarks
A preceding step like "When I find element by label text" is required. For example:
```
When I find element by label text "Text"
  And I find closest element "form"
  And I submit
```
