Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

When updating my config to switch between wezterm.action.Search({ CaseInSensitiveString = "" }) and wezterm.action.Search({ CaseSensitiveString = "" }), the change is not automatically applied. It seems like this is because of the empty string argument. If I change the empty string to anything else, e.g. a space " ", then the config change takes effect.

To Reproduce

1. Update config to use case insensitive search with an empty string argument

   config.keys = {
     {
       key = "f",
       mods = "SUPER",
       action = wezterm.action.Search({ CaseInSensitiveString = "" })
     },
   }

2. Search for something and note the search bar says ignore-case
3. Update config to use case sensitive search with an empty string argument

   config.keys = {
     {
       key = "f",
       mods = "SUPER",
       action = wezterm.action.Search({ CaseSensitiveString = "" })
     },
   }

4. Search again and note the search bar still says ignore-case
5. Change the empty string argument to anything non-empty, e.g. a space " "
6. Search again and note the search bar now correctly says case-sensitive

Configuration

config.keys = {
  {
    key = "f",
    mods = "SUPER",
    action = wezterm.action.Search({ CaseInSensitiveString = "" })
  },
}

Expected Behavior

The change should take effect regardless of whether the string is empty or not
