STR:

1) Enable e10s

3) Switch to RDM

Result: dropdown list is not displayed. It's displayed with e10s disabled.

Does it actually depend on RDM at all?  I see the same difference between e10s on vs. e10s off outside of RDM as well.

Indeed, it's more an issue with e10s, no need of RDM.

There is nothing in the drop-down list. I'm testing this on 54.0a1 (2017-02-14) and the list is empty on e10s, non-10s, and Safari windows. However, visually the empty list looks different on e10s and non-e10s windows.

A even more simplified version of test case for comment 0 is: data:text/html,<select></select>

However, as there's nothing in the drop-down list, I personally would think this is a very edge case. Note, chrome behaves the same as what the current e10s behaviour. If there's something in the drop-down list, e.g. adding "option", then drop-down is displayed as expected. Considering the facts, I am going to mark this as P5 (very very low priority, but will accept a patch). 

Astely, feel free to change it if you have different opinions.
