Steps to Reproduce:

1. Open Command Panel input Toggle, Select any toggle command like workbench.actions.view.problems and call it twice.
2. If there is no accident, the execution of the two commands can open the panel and then close it.
3. Then open Command Panel input Toggle again, select some webview view container command like workbench.action.terminal.toggleTerminal, when the panel is opened, no matter how many times the command is executed, the panel will not close again.

I found the reason, but I don't know how to repair it yet.

When we use the command to call out webview type of panel, document.activeElement the value cannot become webview, but will always be on the last activated element, so isAncestorUsingFlowTo will always return false
