• VS Code Version: 1.59.1
• OS Version: Win10

Bug description:

WebviewPanel.viewColumn does not update when the column is changed by closing all files in a previous column.

Steps to Reproduce:

1. Open file in column 1
2. Open a WebviewPanel in column 2
3. Close file in column 1, shifting the WebviewPanel in column 2 into column 1
4. Check WebviewPanel.viewColumn

Expected Result: WebviewPanel.viewColumn is correctly updated to reflect column 1

Actual Result: WebviewPanel.viewColumn says it is in column 2 until the user performs a tab action like opening or switching tabs.
