Dynamic queue "bug"

This is just something really annoying that I came across, but I'm pretty sure it's not a bug so I didn't post this in Report a Bug. If you make changes to your masteries and then someone dodges the game, the message saying "You have unsaved changes in your masteries. Would you like to save them" pops up. If you click on no as another match pops up, it says that you declined even though you were trying to just undo your mastery page changes. It's really annoying and shouldn't be like that.
