Description

Pasting code from clipboard into the form on the website http://esprima.org/demo/validate.html doesn't work.

Steps to reproduce

Put text into clipboard, e.g. via starting Notepad, typing "123", selecting the text and copying it into the clipboard via Ctrl+Insert.
Open website http://esprima.org/demo/validate.html in the desktop browser (I used Firefox 53.0.2 32-bit on Windows 8.1 Pro 64-bit).
Click inside the field below Syntax Validator checks for mistakes and errors. There will be blinking text caret.
Press Shift+Insert on the keyboard to insert the text from the clipboard.

Expected output

"123" without quotes should appear on the spot where text caret is.

Actual output

Nothing happens. Right-clicking and selecting "Paste" from the pop-up menu inserts the text from the clipboard into the text edit field.

Research direction

Start by reproducing the keyboard paste behavior at http://esprima.org/demo/validate.html in the reported Firefox and Windows setup, comparing Shift+Insert with the context-menu Paste action. Trace the demo's syntax-validator text field handling; done means clipboard text appears at the caret when using Shift+Insert without breaking the existing paste behavior.
