Web Inspector: Elements: "Force Print Media Styles" should not persist across Web Inspector sessions

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

Several people accidentally enabled print stylesheets by clicking the printer icon in the Elements tab
and didn't know what happened and how to change it back.

Don't save "Force Print Media Styles" state to WI localStorage,
so re-opening Web Inspector should always have "Force Print Media Styles" disabled.

This could be a static property of DOMTreeContentView, since it's now the only place it's used. But I'll leave it up to you.

Consider the following case:
1. Open a wikipedia article, say https://en.wikipedia.org/wiki/Metropolitan_statistical_area
2. Click "Force Print Media Styles"
3. Navigate to a different article, such as https://en.wikipedia.org/wiki/U.S._state

Expected:
Print styles stay enabled.

If I make printStylesEnabled a private property of DOMTreeContentView, print styles would reset back to disabled.

I suggested making it a static (class) property. Using a private property would also cause print styles to be reset when removing and adding the Element tab. It's fine as-is in Main.js.

Whoops, I misread it. I still prefer to have a state variable in Main.js.
