In the "Go To File" dialog if you tab to the file types drop down control and change the selection with with either the keyboard or mouse, the list of files immediately changes to reflect the new glob pattern.

Also, if you type in a new glob pattern that is already in the list and hit the enter key, the list of files is updated.

However, if you type in a glob pattern that is not already in the list and hit the enter key, the list of files is not updated. You must must use the arrow key to select a different pattern, then use the arrow key to re-select the desired pattern.
