New line auto-indent does not work while recording a macro

Tested in Notepad++ v6.9.2

OBSERVED:
Generally, when user presses return to start new line from a line of text which is indented (by one or more presses of tab key), the new line inherits/copies the indent from the previous line. This is expected behaviour.
However, if user is recording a macro, then presses return to start new line from a line of text which is indented, the new line starts without any indent.

EXPECTED:
New lines should inherit the indent from the previous line in all circumstances. Recording a macro should not modify program behaviour.

TO REPRODUCE:

1. Start new text file.
2. Press tab to indent.
3. Type some text.
4. Press return. Observe new line starts with the indent from the line above.
5. Start recording a macro.
6. The input cursor should be indented. Type some text.
7. Press return. Observe new line starts without any indentation.
