Resizeable: avoid braking the size of an image

[aleen42]

When an image has both margin and padding, there are two problems:

1. margin has set to the wrapper, but the image's one is not clear when initialising
2. While destroying the resizable widget, the image has resized while setting the width with outerWidth or the height with outerHeight.

Thanks for the report. Does the issue you describe exist when jQuery UI 1.12.1 is used or only with jQuery UI 1.13.0 or newer?

Also, please provide a runnable test case on a platform like JS Bin.

I also didn't notice it was a PR. Changes like that also need tests ensuring the issue is really fixed.

Requires tests. Ideally, please also prepare a test case on JS Bin or similar.

Thanks for reviewing, I will make it later.

@mgol As you can see in the https://jsbin.com/muxihix example, the image has the wrong position after being initialised inside a resizer wrapper.

Here is another correct example after fixing: https://jsbin.com/rinazoq
