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

[Omachi]

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.

It is noted in several places that InDesign does not yet support this.

• `window.alert` in a UXP plugin crashes InDesign 
• Products > UXP for InDesign > Resources > Recipes > Debug

@Omachi Alerts in ID 18.5 has some known issues. Do use console.log or other debugging/logging mechanisms until UD 19.0. We plan to fix these known issues in ID 19.0 which will have UXP 7.2 integrated.

I got it.
