'Insert/edit image' dialog changes empty fields to default values

[hermanschaap]

I first add a picture by uploading it and then clicking 'Send to editor'. Then I click the picture and click the 'Insert/edit image' button. In the dialog, the size is not filled out. I change the image description and click Update. Now, the picture is set to a size of 1x1.
I see two solutions:
1) Add the size (and perhaps some of the other fields) to the image tag when sending it to the editor.
2) Change the 'Insert/edit image' dialog, so it ignores empty fields.

I am using Internet Explorer and Windows Vista. And yes, it looks like it is related to #5087.

Closing as duplicate of #5087. This is also fixed with TinyMCE 3 in Wordpress 2.5.
