        The problem here was that the inner text element of search input was first laid out as
        disabled and thus with a 0-height. This would prevent a hit test to ever reach it, even
        if it's enabled.

        Test: fast/forms/disabled-search-input.html

        * rendering/RenderBlock.cpp:
        (WebCore::RenderBlock::hasLineIfEmpty): Removed a check for textarea that is no longer necessary.
        * rendering/TextControlInnerElements.cpp:
        (WebCore::RenderTextControlInnerBlock::hasLineIfEmpty): Added an override to ensure that
            an empty inner text element is always one-line high.
