Tag Selection doesn't work on Planning

Hello,

in Planning view, advanced filters propose tags as criteria.
But entering tags = <value> doesn't restrict project list to project with tags <value>.

For example, i set tags testselect1 for projet one and testselect2 for project two.
I open planning and create custom filter as "tags contient testselect1".
All projects remains visible :
 

If i quit planning and come back, no project are shown. I need to suppress filter to get project :
 

Regards,

PS : work fine in project list :
 

Thanks,

so, if i use tags to mark some projects i have to reprot it on every project activities.
I see it is not too difficult to do that throught multiple update for activities.

Regards,
