When a post is both "watched" and "deleted", the background color styling for deleted should take precendence

When a post is both "watched" and "deleted", the watched styling takes precedence instead of the deleted styling. In my opinion, it should be the other way around (the fact it's deleted is more important than the fact it's watched).

Specifically, a post that has .s-post-summary__deleted and .s-post-summary__watched will have it's background color set to the watched value.

Here is a screenshot showing four posts:

• a deleted post with red background
• a watched & delete post with the yellow background (this is the one I think should be red)
• a watched post with yellow background
• a normal post with neither watched or deleted

Note that the style appears to come from primary.css instead of stacks.css:

Inspect the .s-post-summary__deleted and .s-post-summary__watched styles in primary.css and stacks.css, starting with the selectors that set their background colors. Confirm the combined classes use the deleted styling, then verify the four post states shown in the issue still have the expected backgrounds.
