I reported a bug to Selenium Team, but was directed here even though it was a problem with their code.
SeleniumHQ/selenium#16618
Description
When executing WebElement.getAttribute('value') in Edge's IE mode on a page with document mode 7 or lower, the following error occurs.
This error also occurs when executing WebElement.isDisplayed().
JavascriptError: Error from JavaScript: 'HTMLFormElement' is undefined

at async C:\myproject\test.js:11:19 {

}
Also, when executing WebDriver.submit() in Edge's IE mode on a page with document mode 8 or lower, a similar error occurs.

Reproducible Code
test.js
const { Builder, Browser, By } = require('selenium-webdriver');
(async () => {
let driver;
try {
driver = await new Builder().forBrowser(Browser.INTERNET_EXPLORER)
.setIeOptions({'se:ieOptions': { 'ie.edgechronium': true }})
.build();
await driver.get('http://localhost:4000/ie5.html'); // this page is documentMode 5
const elm = driver.findElement(By.css('input'));
const value = await elm.getAttribute('value');
console.log(value);
} catch (e) {
console.log(e)
} finally {
await driver.quit();
}
})();

<body>
<form>
<input type="text" value="foo">

</html>The following code is causing this bug.
In IE with document mode 7 or lower, an error occurs because HTMLFormElement is undefined.

For submit() issue, this is because document.createEvent is undefined in document mode 8 and below.
