[Desktop] macOS unfocused window minor UI polish issues

[dndrsn]

Description

On macOS, when a Brave window does not have focus, there are a couple minor UI issues:

1. the window "stoplight" buttons are almost imperceptible
2. the bookmark URL bar icon does not show the "unfocused" state consistent to the other icons next to it

Steps to Reproduce

1. Open a Brave browser window
2. Focus on another application or another Brave browser window with the previous window still visible

Actual result:

Notice that the stoplights have almost no contrast with the window chrome.
Also notice that the bookmark icon is not "dimmed" like the others

Expected result:

For the "stoplight" buttons something more like the OS default:

or like Chrome:

For the bookmarks button, the same lower contrast styling as other buttons.

Reproduces how often:

Easily, always.

@dndrsn What macOS version are you on? I think we're seeing this same issue on Catalina 10.15.7. I'm not seeing the same on Big Sur though.

[dndrsn]

@rebron I am currently using Catalina 10.15.7.

@rebron I am currently using Catalina 10.15.7.

Seeing the same on my machine which is on Catalina 10.15.7 as well. Example:

It's really hard to see the buttons on Brave once it's backgrounded compared to the other applications. Sounds like it was possible fixed/addressed in Big Sur as per @rebron's above comment.

@LaurenWags when you have a few minutes, mind checking to see if you're seeing the same thing on Mojave?

@kjozwiak reproduces on Mojave, dark theme looks better than light theme, but both have the Bookmark icon non-dimmed.
