I have two problems when using a tagfield in grid cells. Here is my fiddle: https://fiddle.sencha.com/#view/editor&fiddle/13af
1. When I click a cell the tag editor appears. Leave the cell without changes and now the cell looks as 'dirty'.
2. I cannot delete tags by clicking their 'cross'. The editor just disappears. I'm still able to use 'backspace' but this workaround does not make my customer happy
