Re: [pgAdmin4][Patch]: RM #2904: As a visually impaired user I needall buttons in the application to have appropriate tooltips for my screenreader to interpret

Unfortunately I think there's been a misunderstanding with this patch, most likely my fault for not being clearer;

- There is no need to add tooltips to buttons that already have text, unless we want to add additional information. For example, on the OK button, we might have a tooltip that says "Apply the changes and close the dialog". That really is optional though, as screen readers could already read the button text (but we should be consistent). 

- We do need to add tooltips to buttons that don't have any text. For example; 

     * dialogue title-bar buttons

     * the "close tab" and "move tabs left"/"move tabs right" buttons that may appear in tab bars

     * the add row button at the top of a subnode control (e.g. to add a column definition)

     * the delete and expand row buttons in subnode grid rows

Sorry for not being clearer about the requirements.
