Hum, I am not sure I like the "auto" type.

It simplify the code for the author, you knows what type you are dealing with. But reading this two lines, I think it makes it harder to read the code.
When I read "auto", my brain start looking for clues to resolve the type before continuing to read.

Maybe part of this is that you are not used to auto yet.

The type is right there, HTMLTableRowElement. If I did not use auto I would have had to repeat HTMLTableRowElement twice on the same line of code.

fast/dom/HTMLTableElement/rows.html seems to be timing out on all the bots now, seems likely this is related?

Oops. OK to roll this out, and I’ll look into it later when I have a chance.
