Undo history gets messed up after viewing the source

[skegel13]

With this plugin enabled, the undo plugin gets messed up. Undoing will go back to when you viewed the source and no more undo history is added after viewing the source. So a lot of data can be lost when using undo after viewing the source.

This seems to occur only in the latest version. I tested the older version and did not run into this issue.

Sorry but i can not reproduce this.

I tried to reproduce...

• made some changes in wysiwyg mode
• switched to source
• switched back to wysiwyg and use the undo button to restore the last changes.

Works as it should be

The problem seems to occur when using the CKEditor builder with the compressed code and this plugin added. I can reproduce it on your demo page as well (https://w8tcha.github.io/CKEditor-TextSelection-Plugin/demoFramed.html).

To reproduce:

• go into the source mode
• go back to wysiwyg mode
• make a lot of changes
• undo (all changes made since coming back to wysiwyg mode undo at once)
• redo (none of the changes from the undo and be redone)

Again, this occurs with the CKBuilder version using compressed code. When installing the plugin manually, I run into another issue which I will post as well (https://github.com/w8tcha/CKEditor-TextSelection-Plugin/issues/16).
