Recently noticed this feature of the forum.
For example, if I am on the send merit screen, select the amount of merit to send, press the
Send button, and then refresh the page through the browser or F5, the merit will be sent again. Although if you do this without a short break, then a window will pop up warning you about sending a merite to the post twice.
This trick will not work if you want to send merit immediately by refreshing the page. The page will simply refresh, and the counter of the merit set for sending will reset to 0. But if you sent the merit by pressing the send button, and then click on the page refresh, it will work and the merit will be sent to the same post again.

I tried to do this with the report window, but it does not work there, only in the merit send window I found this. Tried only in Opera browser.
Is this by design at all or not? Why it happens?
