Parent group is not shown first in search results dropdown menu

Problem

We are trying to invite a group that has more than 20 subgroups to a project. The "Select a group" dropdown list in the "Invite a group" window only shows the first 20 items. Typing the "Parent group" in the "Search groups" field shows me a list of "Parent group / Subgroup 1" to "Parent group / Subgroup 20" elements. There is no pagination and there is no way to set "exact match" (neither a way to invite a group using api, nor the way to transfer groups from another project access settings), so we're unable to invite the "Parent group" to a project.

Proposal

List the parent group first. It is the most exact match until a user continues typing past the group name. This would also apply to subgroups that have a lot of subgroups as well so we should make it a rule that the matching group is shown first before showing subgroups.

For the example:

• Group A
  • Group B
    • Group C

Typing Group A should list in this order:

• Group A
• Group A / Group B
• Group A / Group B / Group C

Typing Group A / Group B should list in this order:

• Group A / Group B
• Group A / Group B / Group C

Additionally, we may want to consider putting infinite scroll on this dropdown as well to show more than 20 items, but lazy loaded.
