Why is JavaScript click not working in Rselenium?

Question

I am trying to scrape a web page with a JavaScript drop down menu in R. I can follow the directions listed here, but nothing happens and no errors are shown. Instead, it gives an empty list:

dropdown <- remDr$findElement(using = "id", "s2id_autogen4_search")
remDr$executeScript("arguments[0].setAttribute('class','select2-input select2-focused');", list(dropdown))
> list()

Also, nothing happens (and no console output) with dropdown$clickElement().

This is somewhat related to this post, but I need to click first to activate the drop down.

There was a mask over it, so I needed to find the mask, click on that, then supply arguments to the dropdown itself:

dropdown <- remDr$findElement(using = "id", "s2id_autogen4_search")
mask <- remDr$findElement(using = "xpath", "//*[@id='select2-drop-mask']") 
mask$clickElement()
dropdown$sendKeysToElement(list("l"))
