Save new expected client size on resize

[und3f]

Hello,

_handleResize() doesn't save new expected size if window was resized which cause a bug if window was resized to different size, and then return back to original (e.g. go fullscreen and back to windowed).
Since the expected client size wasn't changed during fullscreen resize, the _handleResize would not resize window during resize to original size as it would exit because of this._clientHasExpectedSize().

The PR add save of new expected client size to fix the issue

Windows test failed because of windows machine itself, please rerun if needed

Thanks for your contribution, good to see that you included a unit test. Could you please describe the issue you saw before applying your fix?

Resize back and forth between full screen and regular seems to work fine for me. What am I looking for?

Hi, I've rechecked functionality with vnc.html and vnc_lite.html files, and it seems that resize works correctly in those.
I am working on reproducible sample, I suspect that it depends on VNC container element display or other parameters.

What I've noticed: there are two resize handlers which are executed separately: _resize and _handleResize the main difference is that _resize saves new ExpectedClientSize and _handleResize doesn't. For both vnc.html and vnc_lite.html the _resize is called on each container element resize, but in my code only _handleResize is called so the element is not resized after full screen.

The two functions have very different uses. _handleResize() is called when the browser window resizes, and _resize() is called when noVNC receives a "DesktopSize" or "ExtendedDesktopSize" message from the VNC server.

The fact that _resize() isn't called in your case indicates that you didn't receive the triggering messages. Are you using a different VNC server when testing vnc.html?

I am using same VNC server (qemu's VNC with websocket) for all tests.

Than, it is kinda weird that _resize() is executed on html element resize. _resize is calling _saveExpectedClientSize which is why vnc.html doesn't have bug with resizing back to original size).

Is it correct to assume that my test case correctly emulates expected real world RFB behavior for resizing?

I'm not sure what you mean. I don't know the details of your test case. You said you were working on a reproducible sample, do you have something like that?

Sorry I got busy and wasn't able to create clean example. But I've tried latest noVnc and it has the issue fixed, so we can close it
