iOS: Every time you enter a command, the keyboard closes

[dfabulich]

Open https://eblong.com/zarf/glk/glkote/sample-demo.html on iOS, and type "help."

Actual: The keyboard closes. You then have to tap on the input line to open it again. (In games that include a page break, there may be no > prompt at all, requiring the user to guess where to tap on the screen.)

Expected: The keyboard should remain on screen when you type a command.
