Unexpected Newline Chars In Cell Content

If cell data contains a trailing whitespace character, four (4) additional newline chars will be appended to the text node inside of the `dt-cell__content` div. This can cause the `text-overflow: ellipsis;` CSS rule to engage prematurely, and will unnecessarily truncate the content of the cell.

It would seem that this is a result of using a template string to format the cell HTML. I've referenced line 864 of cellmanager.js where this is declared. Collapsing the template string to a single line should fix this issue. If this exceeds max line length, concatenating the variables prior to integrating into the template string may be another option.
