Selenium hover code works in Chrome not Edge

public void Hover()
{
    Actions action = new Actions(BrowserWindow.Instance.Driver);
    action.MoveToElement(WebElement).Perform();
}

This is working in Chrome. Not Edge. I have confirmed with the developer that I am "hovering" over the correct element.

WebElement elem = yourWebDriverInstance.findElement(By.xpath("//*[@class='goog-menu goog-menu-vertical uploadmenu density-tiny']/input"));
String js = "arguments[0].style.height='auto'; arguments[0].style.visibility='visible';";

((JavascriptExecutor) yourWebDriverInstance).executeScript(js, elem);

Which also failed to work. Anyone have any idea what I am doing wrong?

More info.

This is also failing on Firefox. I saw an article about out of date selenium drivers. I have JUST installed both geckodriver and set the Edge driver to auto update according to the documentation. I do not believe I have out of date drivers.

Calling code is

public static void DoCloseActiveTabEntire()
{
    Element tab = new Element(byTab);
    tab.Hover();

    // CLose button is not clickable. Cannot use standard BUTTON for find
    Button close = new Button(byClosePanelButton);
    close.Click();
}

If I set a break point at button close... after the hover attempt, I notice that moving my mouse over the "tab" also does not cause the button to be visible.
