ColorChooserUIController::contentSize is returning a size that is too big.

I'm not sure why this problem happens.  We have a code to adjust position on resizing in PagePopupChromeClient::setWindowRect().

It seems to be because there isn't enough room above the element.

ok, I understand. We have no enough room both below the element and above the element, and the current algorithm in setWindowRect() can't correct the bottom position.

IMO, reposition() should be called in PagePopupChromeClient::setWindowRect(), not in WebPagePopupImpl::resize(), and we can remove the current code of PagePopupChromeClient::setWindowRect().

It seems this change is not related to this bug. Do you need to change WebCore to fix this bug?

It would be too late to call reposition in setWindowRect, because setWindowRect takes the screen rect and we can only know the screen rect by calling reposition.

If we return 0x0 for contentSize we won't be able to see the error message.

We never show the error message to end users as far as we know, right?  This change should be done in a separated patch.

Would you update CalendarPickerElement::contentSize too please?

We can remove WebPagePopupImpl::m_isPutAboveOrigin.

Should be updated.

We had better explain what was wrong.
