snackbar notice is partially hidden under sidebar

[m-e-h]

On post update the part of the snackbar that reads "post updated." is hidden beneath the sidebar.

Steps to reproduce the behavior:

1. Update a post.
2. look at the snackbar.

Screenshots

Desktop (please complete the following information):

• OS: OSX
• Browser: Firefox

Additional context

• It appears that Fix the snackbar notices position #18683 may have surfaced some styles that were previously inactive?

The fixed position in the /edit-post/layout CSS

.edit-post-layout .components-editor-notices__snackbar {
    position: fixed;

is overriding the absolute position in the /snackbar component CSS

.components-snackbar-list {
    position: absolute;

• Is it necessary to even have snackbar styles outside of the snackbar component?

I think this issue is a duplicate of another one I created but I though it was fixed :)

In my experience the snack bar is too far to the left.
