The reason for this is that I often have to resize and move tokens to have them positioned correctly on the grid and the only way to do this is to use the "Is Drawing" option. However, clicking on tokens set to "is drawing" doesn't currently pop up the token information (Icons and bubbles). My suggestion is that any token on the "Objects and Tokens" plane should pop up token information when highlighted, while things on the "Map and Background" plane should not. This would make it much easier to resize and correctly position tokens using "is drawing" and still have access to the useful pop-up token information.
