Fix resizing of the item action column for dynamically added item actions

[makl9797]

If an item action is added dynamically after clicking another item action, for example, the column of the item actions is not resized, which results in an overflow of the icons. Now, the table listens for changes in its DOM tree and adjusts the width of the item action column based on the width of the element containing all the item action buttons.
