Can only use view displays with "page_1" machine name for View field sub-view

STEPS:

1. create view called "View 1"
2. create page display for View 1 called "Page" (machine name should be "page_1")
3. create second page display for View 1 called "Page 2" (machine name should be "page_2")
4. create another view called "View 2"
5. add View field to View 2
   1. (See https://www.drupal.org/node/2794483 for explanation of steps below)
   2. don't configure
   3. click Apply
   4. click newly added view field to configure
   5. select "View 1" from View dropdown
   6. select "Page" from Display dropdown
   7. click Apply
6. repeat step 5 (and sub steps), but this time select "Page 2" from the Display dropdown

PROBLEM:
The view field with View 1:Page field should work fine, but you cannot create a view field for View 1:Page 2. Doing so will cause the following form error: "An illegal choice has been detected. Please contact the site administrator.". My testing suggests this you can only use display's with "page_1" as the machine name for a View field. Furthermore, based on default Core behavior, this means you cannot use a non-page display (a block display, for example) unless you change the display's machine name to "page_1" (I created a block display and changed its machine name from "block_1" to "page_1" and it did not throw the error).

WORKAROUND:
Create a separate view with only 1 display and ensure that the display's machine name is "page_1". This works perfectly well, but it would be bad practice to give non-page displays a machine name of "page_1". Furthermore, it prevents the site admin from efficiently grouping similar displays together under 1 view. For example, I'd like to have a view called "Views Field Views" with all of my sub view pages grouped together under one umbrella. But, given the current bug, I must instead create:

1. Views Field View People Pictures:Page
2. Views Field View People Hobbies:Page
3. Views Field View Employee Employers:Page

instead of:

1. Views Field Views
   1. People Pictures
   2. People Hobbies
   3. Employee Employers
