Display of alert(), confirm(), prompt() in UXP is wrong

The environment is as follows.

• InDesign 18.5.0 Japanese edition
• UXP 7.1.1
• Windows 10 22H2 (19045.3208)

After running the following script, you should see something like the attached image.

// htmlfunc.idjs
alert("message");
let s = confirm("Choose button");
s = prompt("Input your name","");

Is this a phenomenon specific to the Windows edition, or is it a phenomenon specific to the Japanese edition? "Is it just me?"

 or 

prompt() has no text field.
