Image Edit Buttons not available with large images

[Ipstenu]

In visual mode, if your image is larger than your editing area, you can't see the edit/delete buttons:

The image in question is 1200px wide and as you can see by the little white box on the left corner, I did select the image to edit it. You also can't side scroll.

Theme is Genesis, which has no editor CSS styleing. Can reproduce on TwentyFourteen if I remove the editor-style.css

I think the 'error' here is that if there's no editor-style, forcing the image to the right size in editor, the default is show everything. This will be an issue as that file is still only recommended, which means it's possible a number of themes don't yet handle this. I would suggest some sort of default width (god knows how you'd calculate it at this point) to prevent overflow.

Reproduced in Twenty Ten with a 1400px wide image once I removed editor-style, though I am able to side scroll in Chrome and Firefox on OSX to reach the edit button.

I instigated the move to the right. A few days ago I relented and we've decided to move it back to the left, where it was in 3.8.

In 27777:

MCE view controls:

• Move controls back over to the left, as they were before. Wide images and muscle memory have been causing frustration.
• Improve the experience and unify the UI of media view controls. Audio and video views now require an initial click to select before further interaction.
• CSS clean up and organization.
