Change in Version Picker (multiple version) interface

Summary

In one of the latest JIRA updates, there was an unexpected change in how Version Picker (multiple version) custom fields display.

Instead of showing a simple button to click and display the version (filtering as characters are entered), a list of versions is shown in Edit Screen for issues (regardless of whether the users started editing this field).

This is not happening in the Create Screen in most cases, but we can see it when editing the issue.

Also something note is that this bug is currently extremely inconvenient when your project have a lot of versions in them (a pretty common scenario) and you have to scroll through a long list of versions to select them. 

Affected Version:

JIRA 1000.1350.0

Steps to Reproduce

1. Create a Version Picker (multiple versions) custom field
2. Add it to a project’s Edit and View Screens
3. Create an issue using these screens
4. Edit it

Expected Results

The versions are only listed when the field is selected, just like Fix and Affects Version/s fields.

Actual Results

A permanent list of versions is displayed, taking up space.

Notes

Custom fields which were created earlier, show with the "old" design

Workaround

Use cmd + click to select multiple versions as in:
