It seems wrong not to call .toInt() on the LayoutUnit here since we're
ultimately assigning it to an int.

It'd also be better to have an IntSize for the expected page size instead of
separated components.

Made it float, because resizePageRectsKeepingRatio takes floatsize
Done.

+            int expectedPageHeight = std::min<float>(documentRect.height().toFloat(), pageSize.height() * maximumShrinkFactor);
             FloatSize maxPageSize = m_frame->resizePageRectsKeepingRatio(FloatSize(originalPageSize.width(), originalPageSize.height()), FloatSize(expectedPageWidth, expectedPageHeight));
             pageLogicalWidth = horizontalWritingMode ? maxPageSize.width() : maxPageSize.height();
             pageLogicalHeight = horizontalWritingMode ? maxPageSize.height() : maxPageSize.width();
