• I have read the FAQ section, searched the open issues, and still think this is a new bug.

Describe the bug you encountered:

When I search for password entries, the search results are prefaced with an icon indicating whether the entry has expired, but they are nearly impossible to see because they show up as white icons on a light grey background on my phone.

Describe what you expected to happen:

Icon with proper contrast.
