Calc: Auto-fit column and row don't follow line break

In cell A2, I used ‘Ctrl’+‘Enter’ after 1st, 2nd and 3rd sentence. And I used ‘Enter’ after 4th sentence. Row 2 didn’t extend the height to fit the content automatically.

And neither auto-fit column nor auto-fit row is disable.

Help me please !

| LO 6.4.0.0.alpha0+ |

This is not reproducible with 6.3.0.2, which is still just a release candidate of soon-to-be-released (and will-be-new-fresh) version 6.3. But you use development build of current master toward 6.4 (which will only be released next February) - not even alpha 1 - which is actively developed, with expected lots of bugs, which only get polished close to release… so - well, you are on your own using that. It would be nice if you do something to find the roots of the problem (e.g. using bibisect tool) or - even better - fix that (joining developers). But not much more that you could expect here.

By the way - I confirm your observation with my build of master.

Repro with 6.4 but not with 6.3, looks like a regression. Please report the issue on bugzilla Create a bug report, an edit your question to add the bug number so it can be confirmed.
