"Filer: Auto Sync Terminal Folder" does not work

[Windows11，WindTerm_2.6.0_Windows_Portable_x86_64.zip]
When Filer panel is hidden and a session is connected, after several commands(e.g. the "grep" command) run in the console, open the Filer panel, the folder does not auto sync. But if opening the Filer panel before no command runs, "auto sync" works fine.

Now have to change bak into pre-release 2 temporarily.

Reproduce on Windows 11 with WindTerm_2.6.0_Windows_Portable_x86_64.zip: connect a session, leave the Filer panel hidden, run several console commands such as grep, then open the panel. Compare this with opening the panel before running commands. Done means the Filer folder auto-syncs in both cases without the temporary pre-release workaround.
