Inline image replacement in Post Editor does not replace image

[Ipstenu]

Tested on 4.5-RC2-37173 with the following steps:

1. Make a new post
2. Add m08aGa1nAM.png to post as medium image
3. Click to REPLACE image
4. Click 'Edit Original'
5. DELETE from this window
6. Upload new m08aGa1nAM.png

At this point, I see the OLD image in the edit page. As soon as I hit 'save draft' however, it shows the correct image.

Tested on WP 4.4.2 and the image replaces as expected, no need to save.

It looks like whatever ajax magic is supposed to refresh that image isn't happening until save.

Think I'm missing or misunderstanding a step when trying to reproduce.

5. DELETE from this window.

I'm in the modal in the image file editor and cannot delete from there. Tried editing the image then deleting it and replacing it, all works as expected.

Another question: if the image is deleted in step 5, and another image with the same name is uploaded, and the old one is shown in the editor, where the old one comes from? At this point it is not on the server any more? It is possible some sort of "network cache" is interfering, as old and new images have the same name. Not sure why it only happens sometimes though.

I gave the unclear directions

3. Click to REPLACE image
4. Click 'Edit Original'

So on the post editor, click the pencil and then press the box to replace the image, not edit.

3. Click to edit the image
4. Press REPLACE button

The replacement window. Drag/drop the new image with the old image name.

Replying to Ipstenu:

Thanks, yeah, can see it now.

A new bug is that the right sidebar (image info and settings) doesn't get refreshed/cleared out after deleting an image. Seems caused by the Backbone update as far as I see.

The image not refreshing after replacing it is tougher. Was able to reproduce in 4.4 too, but less frequently. Seems the browsers "hold onto" the image in the editor despite that it is no longer on the server. Can happen more reliably after deleting an image, no need to replace. Steps:

1. Open the media modal, upload an image and insert it in a post.
2. Edit the image, and delete it permanently.
3. Close the modal by clicking outside or on the top/right close button.

At this point the image is displayed in the editor. After switching to the Text editor and back (i.e. forcing TinyMCE to reload the post content) the image is still displayed, although it is not on the server any more. Only after saving a draft/reloading the page the image will be displayed as missing.

I was looking into reproducing this issue today, but I can't seem to reproduce it. @Ipstenu do you happen to remember any details on this one?

I am marking this as a close candidate, but since a lot of the media modals are reused within the block editor, we should be sure the issue does not still exist and carries over.

This doesn't seem to happen on 5.2.1! Excellent.

Thanks for the follow up!
