Perfect Timing Shop Bug [Gameplay]

When using the Perfect Timing rune. When you go to sell the stopwatch which was nerfed to 20g. The game client briefly flashes 200g before it reverts to 20g. This isn't the problem. The problem is the shop illuminates everything you can buy with the 200g. So for instance, if you have 700g and sell the stop watch, it will flash 900g then drop to 720g. However the shop will still illuminate items like Vampiric Septer that you'd be able to purchase with the 900g.

To reproduce, take the rune Perfect Timing. Sell the temporary stopwatch to the shop. Notice how much more stuff is illuminated. Can be reproduced 100% of the time.

Additional notes. This bug is not new, it is a minor inconvenience that was mildly annoying the first time you experience it. It has now been 2 years since the first time I experienced the bug and it is now really aggravating that it has not been fixed and surely anyone with Perfect Timing has noticed this. Spam clicking an illuminated item and it not going into your inventory before you look into the corner and notice you don't have enough gold can be very aggravating, especially in a game like league where every second is critical.
