💡 Description

• Add guard to avoid capturing an incorrect screenshot for homepage tabs
• The problem is that contentContainer is a shared view that always reflects the currently selected tab's content. When navigating away from a homepage tab, the screenshot is dispatched asynchronously, when it executes, contentContainer may already be showing a different tab's content like in this bug a new opened private tab, causing the wrong screenshot to be stored on the original tab.
