Unable to execute .txt script pasted into Editor. Execute Statement and Execute as Script buttons (4364045)

I used to be able to drag a '.txt' file or open a '.txt' file in the editor and then be able to execute it. Now the file opens in a Text tab and the execute buttons are grayed out.

This change was intentional. The Text tab style is a dumb text tab that is designed for lightweight editing and '.txt' are associated with this tab style, by default.

It is possible to customize the tab styles and add the TXT extension to the SQL tab style if you use '.txt' extension for scripts on a regular basis. (See attached document for instructions)
