Bug 155216 – focus() / blur() should be on HTMLElement / SVGElement, not Element

• Component: DOM
• Status: RESOLVED FIXED

[Chris Dumez]

focus() / blur() should be on HTMLElement / SVGElement, not Element:
- https://html.spec.whatwg.org/multipage/dom.html#htmlelement
- https://www.w3.org/TR/SVG2/types.html#InterfaceSVGElement

Chrome and Firefox match the specification.

How about MathML elements?

I guess this is OK, but it seems kind of weak; sort of old fashioned. I suppose there are a lot of things on HTMLElement that are useful on MathML and SVG elements and it’s a little strange that we do this by putting the functions separately on each of those classes. I wonder what the concept is for the future about accommodating new types of elements in that won’t support these operations.

I cannot find any IDL files for MathMLElements.

So, the specification does not seem to indicate that MathMLElement has either focus() or blur():
https://www.w3.org/TR/MathML2/appendixd.html

I have checked that in Firefox and Chrome, MathMLElement does not have focus() / blur() either.
