Open tab in background doesn't work

[Exagone313]

When the tabs affected by this add-on are set to be opened in background, the tabs are in fact opened in foreground. I didn't know this was the intended behavior.

The code that should set the previous tab as active has no effect:

pinned-tab-fix/background-script.js

Lines 49 to 51 in fdd975f

	if (loadInBackground) {
	browser.tabs.update(lastActiveTab.id, { active: true });
	}

Proposed solution:

• open tabs in foreground by default
  • existing users will see a break of behavior, I don't know if the property can be reset (otherwise it can be renamed)
• fix the bug

Note: I have working code that fixes the bug, but I'm concerned about the breaking change. e8e0392
Note 2: With the fix, it will noticeably move to the new tab then back to the previous tab, but I don't believe it can be corrected (an option could be added to do not set the new tab as active).

for me, it is the other way around - when I click "new tab" with browser.tabs.insertAfterCurrent enabled in about:config, it does not switch to the new tab as expected
