Autocomplete fails with multiple value field text field

I have a content type (node) with a text field (field_text_multi) that can hold several values.
My view is displaying correctly field_text_multi
This is a simple view (no relation, no contextual filter)
If I add this field as a filter, with the "contains" operand and if I check "use autocomplete"
Then, the filter is working as expected excepted that there is no autocomplete list...
(On the same view, if I add an autocomplete filter on the title node then everything is perfect)
