Comment (by iCaleb):

 I can replicate consistently. This also occurs with the `<!--nextpage-->`
 tag.

 It has to do with the content.replace() call here:
 https://github.com/WordPress/WordPress/blob/6ffafa5bc7124dd58a292720fea49465297f452c
 /wp-includes/js/tinymce/plugins/wordpress/plugin.js#L108

 It also matters where your cursor is exactly. For example, if your cursor
 is between the `p` and the `a` in `nextpage` before you switch back to the
 visual editor, you end up with this in the content:

 `<!--nextp<span data-mce-type="bookmark" style="display: inline-block;
 width: 0px; overflow: hidden; line-height: 0;"
 class="mce_SELRES_start"></span>age-->`

 And when it is in between the `m` and `o` in `more`:

 `<!--m<span data-mce-type="bookmark" style="display: inline-block; width:
 0px; overflow: hidden; line-height: 0;"
 class="mce_SELRES_start"></span>ore-->`

 A google search for `"data-mce-type="bookmark"` shows many other similar
 issues.
