combobox inside multi-value data load bug

Summary

uibuilder-combobox inside a uibuilder-multi-value does can only load items from the first page of the datasource.

Steps to reproduce

Checkout branch: mcve/combobox_inside_multi_value_data_load_bug

Start the example app -> Navigate to the following example: Form / Multi value / Multi-value with bean items -> select the "First Holder" from the holder combobox -> 0-49 items can be loaded into the "Label combobox" while items 50-99 will be empty. As you can see it on the attached picture.

What is the expected correct behavior?

All the label comboboxes should load assigned value, wether items are on the first page of the datasource or not.
