[Evolution] Scroll wheel not work until text is selected

[Jose Legido <jose legido com>]

Hi.

In the "Message preview" only works mouse scroll wheel over headers
and scroll bar, but not over the text message.
Searching information I found something similar:

https://bugzilla.gnome.org/show_bug.cgi?id=699574#c10

but my behavior is different. When I select some text in Message
preview, mouse wheel starts work.
If I close evolution, I have to select some text again.

Is the same bug?
should I open another bug?
