[IE11][CF] Styling could not be reapplied on a simple click

[kkrzton]

Steps to reproduce

Can be easily reproduced on /tests/plugins/copyformatting/manual/safaricolor (for both editors).

1. Put caret inside first paragraph e.g. Text witho^ut any format.
2. Click Copy Formatting button.
3. Click on the last word (Orange) inside last paragraph (styling will be removed).
4. Click on the still styled word inside same paragraph e.g. Text with Bac^kground Colour Orange.
5. Click Copy Formatting button.
6. Click on the last word (Orange) inside last paragraph.

Expected result

On the second click styling should be copied, so word Orange should be styled same as rest of the paragraph.

Actual result

On the second click, styling is not applied.
