The Column Resize Selection Area Is Too Narrow On The Markdown Dashboard Widget

[cccs-Dustin]

Within the edit mode of a dashboard, hovering over the far right edge of the Markdown widget only shows the “move” cursor, not the “resize” cursor. This is inconsistent with the other types of charts, as for the rest of them, the "resize" cursor appears when one hovers over the far right edge.

The screenshot below is what you see when you try to adjust the width of a Markdown widget (you see the "move" cursor and not the "resize" cursor).

How to reproduce the bug

1. Go to a dashboard which contains a Markdown widget, or add a Markdown widget to a new or existing dashboard.
2. Select the "Edit dashboard" button (pencil icon in the top right of the page).
3. Try to adjust the width of the markdown widget.
4. You will notice that it is not easy to get the "resize" cursor to appear.

Expected results

When you go to adjust the width of the Markdown widget, the "resize" cursor should appear and thus allow you to make the widget larger or smaller.

Actual results

When you try to find the area that gives you the "resize" cursor, it does not seem to exist, or it is so small that it takes a while to get your cursor lined up with it.
