When trying to send the Enter Key to Web Browser using the Press and Release function, it does not work. This function works with any other key that you try to send.
A repro project is attached that has the steps setup.
This was reported and tested in 4.24.3 (CL-11590370). This was reproduced in 4.23.1 (CL-9631420), 4.25 Preview 1 (CL-11723679), and Main 4.26 (CL-11724764)
Results: The node which sends the Enter Key will return true, but nothing will happen. The text entered in a web browser's text box will NOT be committed (or will not break a line).
Expected: The text typed was committed, or the cursor is in the next line.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-90000 in the post.
