When the popover component is opened, transform: translate is fixed to (0px, -200%).

Even if I reinstall the Popover component, the same thing happens. What should I do?
When using dropdownmenu and date picker, it looks like this.

this is my datepicker code

"use client";

import * as React from "react";
import { format } from "date-fns";
import { CalendarIcon } from "lucide-react";

import { cn } from "lib/utils";
import { Popover, PopoverContent, PopoverTrigger } from "./popover";
import { Button } from "./button";
import { Calendar } from "./calendar";

export function DatePickerDemo() {
  const [date, setDate] = React.useState(new Date());

  return (
    <Popover>
      <PopoverTrigger asChild>
        <Button
          variant="outline"
          className={cn(
            "w-[240px] justify-start text-left font-normal",
            !date && "text-muted-foreground"
          )}>
          <CalendarIcon />
          {date ? format(date, "PPP") : <span>Pick a date</span>}
        </Button>
      </PopoverTrigger>
      <PopoverContent className="w-auto p-0" align="start">
        <Calendar
          mode="single"
          selected={date}
          onSelect={setDate}
          initialFocus
        />
      </PopoverContent>
    </Popover>
  );
}

Same here, in latest firefox & chrome. Can reproduce with simply:

npx shadcn@latest add button popover

import { Button } from '@/components/ui/button';
import { Popover, PopoverContent, PopoverTrigger } from '@/components/ui/popover';

export default function App() {
  return (
    <Popover>
      <PopoverTrigger asChild>
        <Button variant="outline">Click Me</Button>
      </PopoverTrigger>
      <PopoverContent className="w-80">Hello World</PopoverContent>
    </Popover>
  );
}
