Change case does not work correctly in table

I don’t know if this is bug or not:

When changing case in table cells, selected text is changed, but the rest of the cell as well.

Is this something that happen to me only or?

I am not sure the table context is a factor. The video appears to illustrate bug fdo#49033.
