Bug 256811

Currently in WebKit if a textarea has overflow auto and overflow-wrap normal, it includes the scrollbar thickness in the logical height. This check doesn't exist in Firefox and no longer exists in Chrome as of https://chromium.googlesource.com/chromium/src/+/18481ffa332076e58fd9adbbea2062c2ba087dfb It would be good to remove it from WebKit too for interop purposes. if ((isHorizontalWritingMode() && (style().overflowX() == Overflow::Scroll || (style().overflowX() == Overflow::Auto && innerText->renderer()->style().overflowWrap() == OverflowWrap::Normal))) || (!isHorizontalWritingMode() && (style().overflowY() == Overflow::Scroll || (style().overflowY() == Overflow::Auto && innerText->renderer()->style().overflowWrap() == OverflowWrap::Normal)))) logicalHeight += scrollbarThickness(); The above code inside of RenderTextControl.cpp would become something like the below code: if ((isHorizontalWritingMode() && style().overflowX() == Overflow::Scroll) || (!isHorizontalWritingMode() && style().overflowY() == Overflow::Scroll)) logicalHeight += scrollbarThickness();
