Inserting tags with the insertTags funcition (toolbar.js) behaves oddly in Chrome atm.
The text is not insertet at the cursor position, but a the end of some row above.
The selection is also wrong and usually spans over multiple (non-selected) rows.
Occurs directly when editing, but after a while it works.
Chrome 58.0.3029.81 (64-bit) on Win 8.1 and OSX
MW 1.25 and on MW.org
