Repro:

• Set "terminal.integrated.tabs.description": "${task}${separator}${local}${separator}${shellPromptInput}${separator}${cwdFolder}"
• Type a command out that ends in a space, notice the tab shows a space before the | in the tab
• Reload the window, 🐛 the space before the | is gone

This should use the cursor position after reload to add trailing whitespace
