Safari on MacOS (Mojave) can't open newly created files
Assume I first open Safari, go to gmai.coml to check my emails.
Then I creat a local file using any app such as TextEdit.
Then I try to use Safari to open that file (to use the file as an attachmen to an email),
but the newly created file is not visible!
If I directly open Finder, the new file is there and can be opened with any apps.
But Safari just couldn't see the newly created file.
I know if I quit Safari, then restart it, that file is visible now. But that is inconvenient sometime.
This is clearly a bug inside Safari.
Other web browsers, such as Firefox, doesn't have this problem.
