Solution to fix it for WebView, note it handles only space character , but you can extend mapping KeyEvent.KEYCODE_SPACE => keyCode.

class MyWebview: WebView {
    override fun onCreateInputConnection(outAttrs: EditorInfo): InputConnection? {
        return BaseInputConnection(this, true)
    }

    override fun dispatchKeyEvent(event: KeyEvent?): Boolean {
        val dispatchFirst = super.dispatchKeyEvent(event)

        // Android sends keycode 229 when space button is pressed(and other characters, except new line for example)
        // So we send SPACE CHARACTER(here we handles only this case) with keyCode = 32 to browser explicitly

        if (event?.keyCode == KeyEvent.KEYCODE_SPACE) {
            if (event.action == KeyEvent.ACTION_DOWN) {
                evaluateJavascript("javascript:keyDown(32)", null)
            } else if (event.action == KeyEvent.ACTION_UP) {
                evaluateJavascript("javascript:keyUp(32)", null)
            }
        }

        return dispatchFirst
    }
}
