[FIXED-1182] column resize icon displays when it should not

[rspaeth]

when the first column is defined as hidden in a configuration, the resize icon displays over the left side of the left most column, but does not perform any resizing. Even if the first column is defined to display and the user hides it sometime in their interaction with the grid, the resize icon displays for the second (now first) column.

how to reproduce:
-use the code below. note that the first column is hidden in the config file for this example
-place the cursor over the left side of the first visible column
-notice the resize icon
-try to resize

result:
when trying to resize nothing happens

if the hidden column is displayed, the icon does not show as expected

expected result:
no icon or the ability to resize the column

version: 3.2.2 release
