[Bug] Image Size Cannot be Set

[cyfung1031]

Example:

https://greasyfork.org/en/scripts/468740-restore-youtube-username-from-handle-to-custom

Previously we can use <img src="xxx" width="xxx"> to set the size of the image. Now the width attribute is removed in the HTML final code. (i.e. <img src="xxx">) The width control is disabled.

Please fix.
