Would you be happy if only your tax rate went up, or is that tied to other people in your tax bracket also paying out more and thus, presumably, benefiting society more than they would by hoarding/wasting the money?
I don’t think it’s weird that people don’t behave “rationally” in the crude sense of that word[1]. But it seems really weird to be happy about your tax rate going up. Consider the alternative: for example, you could give the money to charity that works in developing countries. So there seems to be two explanations:
(1) Either you consider yourself prodigal and want an authority to take care of your spending for you.
(2) Or you have weirdly framed your views for extra shock value; and you simply dislike inequality and suffering; and you think that the state can help alleviate some of it by reallocating social resources in a socially beneficial manner. And you think it would be just if they also would take some money from you, even if it’s done by force. There is really nothing surprising about this view; I would rather say it is very popular. (And, unfortunately, for most people that feeling for equality doesn’t spread beyond their own country.)
[1] In principle, rationality in economics doesn’t necessarily imply egoism. It just means that the choices made by a person have nice properties like completeness or transitivity. Whether your choices maximize your consumption, consumption of other people, the scientific progress or the amount of plastic in the world ultimately doesn’t matter.

Why not both? I am happy for my tax rates to go up - indeed, I will vote for any political party that advocates this - and donate to developing countries (and also food banks in the UK because we are shamefully bad at being a developed country.)
The third option is that it genuinely makes me happy, because it implies we're taking care of everyone more. My money going to charity is fine. My money going to taxes implies other wealthy people like me are also chipping in for schools, healthcare, etc.
The idea that we have to use force to take money away from people to take care of those in need doesn’t make me genuinely happy. That is rather depressing that we cannot solve those problems without ultimatums based on violence. Necessary? Maybe. Wholesome? Not really.
I'm happy when my tax rate goes up. This apparently really bothers people. (Me being happy about it.)
