            Bug ID: 227107
           Summary: SVGGraphicsElement.getBBox misses checking the type of
                    its param
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: zyscoder at gmail.com

Steps to reproduce:

(1) Open a tab and navigate to https://outlook.live.com/;
(2) Open Devtools and run the following code in the Console:
```
document.getElementsByTagName('svg')[0].getBBox(true);
```
Actual results:

This code would be evaluated successfully without throwing any exceptions.

Expected results:

As https://svgwg.org/svg2-draft/types.html#__svg__SVGGraphicsElement__getBBox says, the getBBox method asks an SVGBoundingBoxOptions type value as its parameter. Checking for the type of param should be added and this code should throw a TypeError exception, like what Firefox does.
Firefox: `SVGGraphicsElement.getBBox: Argument 1 can't be converted to a dictionary.`
