Bug 265115

Hi Team,

While looking into 'browser specific failures' on WPT, I noticed that we fail few test cases 'cssom-view\idlharness.html' around 'moveTo' and 'moveBy' (there are few more but it is better to tackle one by one - easier to revert in case of any issue):

WPT Test Case: https://wpt.fyi/results/css/cssom-view/idlharness.html?label=master&label=experimental&aligned&q=safari:fail

Web-Specification: https://www.w3.org/TR/cssom-view-1/#extensions-to-the-window-interface

By doing changes in 'LocalDOMWindow' and 'Source/WebCore/page/LocalDOMWindow+CSSOMView.idl', I was able to progress few of them but I am not sure whether it is intentional to hold-off so I just wanted to raise bug.

>> Source/WebCore/page/LocalDOMWindow+CSSOMView.idl:

From:

undefined moveTo(optional unrestricted float x = NaN, optional unrestricted float y = NaN); // FIXME: Parameters should be mandatory and of type long.
    undefined moveBy(optional unrestricted float x = NaN, optional unrestricted float y = NaN); // FIXME: Parameters should be mandatory and of type long.

To:

  undefined moveTo(long x, long y);
    undefined moveBy(long x, long y);

>> Source/WebCore/page/LocalDOMWindow.cpp (To):

void LocalDOMWindow::moveBy(int x, int y) const
{
    if (!allowedToChangeWindowGeometry())
        return;
    CheckedPtr page = frame()->page();
    auto fr = page->chrome().windowRect();
    auto update = fr;
    update.move(x, y);
    page->chrome().setWindowRect(adjustWindowRect(*page, update));
}
void LocalDOMWindow::moveTo(int x, int y) const
{
    if (!allowedToChangeWindowGeometry())
        return;
    CheckedPtr page = frame()->page();
    auto fr = page->chrome().windowRect();
    RefPtr localMainFrame = dynamicDowncast<LocalFrame>(page->mainFrame());
    if (!localMainFrame)
        return;
    auto sr = screenAvailableRect(localMainFrame->view());
    fr.setLocation(sr.location());
    auto update = fr;
    update.move(x, y);
    page->chrome().setWindowRect(adjustWindowRect(*page, update));
}

>> Source/WebCore/page/LocalDOMWindow.h (To):

void moveBy(int x, int y) const;
    void moveTo(int x, int y) const;

Just wanted to raise so I can get insight / plan. Adding 'BrowserCompat' tag since only WebKit / Safari is failing them and 'WPTImpact' because it has impact on WPT.

Thanks!
