After image insertion：

Trying to reproduce in Chrome 58.0.3029.81 (64-bit) Win10:

Initial content is:

http://localhost/content/uploads/2017/01/IMG_20170106_141203.jpg

This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence.

After Ctrl+X (cutting) the URL, the content is:

This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence.

(Note the white space at the top. This is now an empty paragraph.)

Opening the media modal, selecting Insert from URL, pasting the URL and clicking Insert, the content (from the Text editor tab) is:

<img class="alignnone size-medium" src="http://localhost/content/uploads/2017/01/IMG_20170106_141203.jpg" width="3264" height="2448" />

This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence. This is a test sentence.This is a test sentence.This is a test sentence.

All seems to be working properly here. Perhaps I'm misunderstanding some of the steps to reproduce it.

Please do not put blank lines in the above text and below text.
TinyMCE 「TEXT MODE」Please try the same action.
The phenomenon occurred in the Japanese version.
Maybe there is a possibility of multibyte problem.

Ah, I see it now. This is in the Text editor (textarea), not in TinyMCE.

Can reproduce it there. Very strange... Possibly a Chrome bug? Another way to reproduce:

1. Add some text in the Text editor. For example: This is a test sentence..
2. Delete or cut This. Can be with backspace, forward-delete, Ctrl+X, etc. Has to be several chars long and at the very beginning.
3. Insert something from the media modal, doesn't matter local or remote, image or video.

At this point few more chars of the initial text are removed/overwritten.

@dreative thanks for the ticket. Trying to patch.

Edit: the number of the overwritten/missing chars is the same as the number of deleted chars. Starting to look more like a Chrome bug.
