Copied text from a StringConvertibleMatrixView does not include every selected cell

[mkommend]

When cells are selected with the cursor keys or pos1, end, page up and page down keys some values are not included in the copied text.

Steps for reproduction 1) Select any cell 2) Hold shift and press page up to select every cell upwards until the first row 3) Copy values with ctrl+c 4) Paste into excel or editor. Only two values are copied

Another issue is when multiple different areas are selected the not selected cell between are omitted and the content is pasted without any white spaces in between. This behavior should also be corrected.
