when underlining text behind a bullet, depending on when underlining the text

- sometimes the bullet ist not underlined
- sometimes the bullet and the autospace after the bullet is underlined
- sometimes the bullet is underlined and the autospace after the bullet is not
underlined 

(see attaced file for example and step-by-step reproduction)

step-by step reproduction as pasted in the attaced file:

add a bullet with some text, select the WHOLE text and press (CTRL+U). this will
underline the whole text and the whole bullet:

now press CRTL+U to deactivate „underline“ and add another bullet with some
text, select THE FIRST PART of the text and press (CTRL+U). this will underline
the selected part text and not the bullet:

now activate „underline“ (press CRTL+U) and add another bullet with some text,
(it should all be underlined automaticly) then select THE LAST PART of the text
and press (CTRL+U). this will remove the underline from the selected part. the
WHOLE Bullet will still be underlined:

now activate „underline“ (press CRTL+U) and add another bullet with some text,
(it should all be underlined automaticly) then select THE FIRST PART of the text
and press (CTRL+U). this will remove the underline from the selected part. the
Bullet will PARTLY be underlined:

this also happens with „bold“ and Numbering


i would prefer the Bullets to be always „normal“ no matter what the text is
formatted like. Because when making a list with some „normal“, some „underlined“
and some „bold“ text, all the bullets should be formatet the same. when the user
wants a bold /other bullet, he should/can select the wanted bullet from the menu
(Format - Nummerierung/Aufzählung...) (In english I guess it is something like 
 (Format - Numbering/Lists...))
