Recording a macro with a tab does not work after upgrading to 12.7 (4305806)

The option for Tabs and Indentation is set to Smart Tabs. When recording a macro, that includes tabs, it does not work as expected in 12.7 e.g.

field1 [tab] [tab] [tab] varchar2(2000),
field2
field3

If recording a macro (starting just after field2) -  tab | type Varchar2(2000), | down arrow | begin key | end key

Using smart tab, it should look like this:

field1                       varchar2(2000),
field2                       varchar2(2000),
field3                       varchar2(2000),

Instead it looks like this: 

WORKAROUND

switch to option 'Spaces' instead of 'Smart' for 'Tabs and Indentation' option.
