Element is not currently visible and so may not be interacted with

This page was somewhat helpful, but did not mention the "transform" style needing to be checked. Then I found this fellow using C# who mentioned the transform value. When I put the two together I came up with this solution:
((JavascriptExecutor)driver).executeScript(
   "arguments[0].style.transform = 'none';",
   myFavoriteElement
);
After setting transform = 'none', myFavoriteElement.sendKeys() did not fail with the infamous error:
Element is not currently visible and so may not be interacted with(..)
So I guess we should add transform != 'none' to the list as follows:
  • visibility != hidden
  • display != none (is also checked against every parent element)
  • opacity != 0 (in rc2 this is no longer checked for clicking an element)
  • height and width are both > 0
  • for an input, the attribute type != hidden
  • transform != 'none'
This issue was found using selenium.version = 2.35.0

NOTE: myFavoriteElement was an input type=file generated by the PrimeFaces fileUpload tag. PrimeFaces 4.0 looks like it introduced the transform. Also, when I checked to see what the transform value was before setting it to none, it logged: myFavoriteElement.getCssValue("transform") = matrix(4, 0, 0, 4, -300, 0).

Hope that helps.
