Description:
When editing cell containing wrapped or multi-line text, highlighting across lines, then delete continues to display deleted text on lines after cursor.

Even just backspace key from the end of the line will leave residue behind.

Cell is not refreshed after delete characters.

First noticed in version 7.2.5.2(x64) for Windows 10 after upgrade from version 5.

After press Enter or leave the cell, the display refreshes and is correct, but during the time of editing it gets very confusing.

Steps to Reproduce:
1. in a cell, type: "abc", press Ctrl-Enter to start new line, type "def", press Ctrl-Enter, type "ghi"
2. Position cursor in first line between "b" and "c"
3. Hold shift key and down-arrow twice to select the "c" "def" and "ghi"
4. Press Delete key



Actual Results:
Will see:
ab
def
ghi

the "def" and "ghi" have been deleted but continue to display, even if continue editing the cell these trailing characters remain.

Expected Results:
Should only see:
ab


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Workaround: Pressing Enter key or moving off of the cell will cause the cell to refresh and display correctly.

Can also reproduce by typing a long sentence in a word-wrap cell, until it wraps a few times then backspace.

Note: The text/formula editing box above the sheet displays correctly.

I did not notice this in version 6.3.4.2, only after upgraded to version 7.2.5.2
