Short description of error
Some operations such as UV editing and change of bake mode do not "take" until Edit mode is exited.

Exact steps for others to reproduce the error
• Start with the default scene and select the cube
• Assign a material to it that has an Image Texture node with a selected texture for output (so it can be used for baking)
• Hit Tab to enter edit mode, and mark seams on the cube
• Go to the UV editor, select all faces, and unwrap it
• Click Bake: The baked texture will not match the UV map but fill the enter texture

• Hit Tab to exit Edit mode and click Bake again: The baked texture now matches the UV map

Expected behavior: The baked texture should match the UV map without the need to exit Edit mode.

Also:

• Hit Tab to reenter Edit mode and move the UV map
• Click bake: The baked texture will not match the UV map
• Hit Tab to exit Edit mode and click Bake again: The baked texture now matches the UV map

Expected behavior: The baked texture should match the moved UV map without the need to exit Edit mode.

This apparently affects other, related operations as well:

• While in Edit mode, change the Bake mode to UV
• Click Bake: The texture is baked correctly
• Change the Bake mode back to Combined
• Click Bake: The is not baked correctly but still uses the previous mode (UV)
• Hit Tab to exit Edit mode
• Click Bake: The texture is baked correctly

Expected behavior: The baked texture should match the selected Bake mode without the need to exit Edit mode.

Note: This affects not only UV mode but several other Bake modes, such as Diffuse Color, Glossy Color, Normal, etc. I have not tested all modes.

Not quite sure this is normal behavior indeed… @dfelinto, @Sergey, thoughts?

The comment in code says we can't bake in edit mode, so guess it's just a know limitation.

If baking is not supposed to be available in Edit mode, perhaps the Bake button should be disabled? However, it would be probably be a better solution if baking remains available and the reported issues are resolved. It would be a time saver and perhaps also more in keeping with Blender's overall UI philosophy?
