Material UI Tooltip Stays Open after triggered Dialog is closed
set disableFocusListener={true}
according to this doc https://material-ui.com/api/tooltip/
See issue #9624:
This is the expected behavior. It's done for accessibility considerations. You have two options, either disable the tooltip response to focus events or disable the dialog restore focus behavior.
1. Disable the tooltip response to focus events (docs)
<Tooltip disableTriggerFocus={true} />
2. Disable the dialog restore focus behavior (docs)
<Dialog disableRestoreFocus={true} />
