Using issue count progress in Advanced Roadmaps shows estimation units instead

Issue Summary

If a user adds the "Progress (issue count)" progress field to a plan, the progress bar shows the progress bar using the estimation unit of the plan (story points or time estimation) instead of showing the issue count. The documentation Monitoring progress of work says:

If you hover on the progress bar of a parent issue, the breakdown of work will take into account the number of issues in the different status categories, the total number of issues in the plan, and the percentage of the number of issues in each status category against the total number of issues.

Steps to Reproduce

1. Create a plan using at least one project as the issue source
2. Make sure your plan has some epics with stories under it
3. Transition different issues from this project used in the plan to different statuses
4. In the plan's view, click on Fields, search for Progress (issue count) and click on it to add this to the plan's view
5. Click the progress bar next to an epic

Expected Results

The progress bar shows the number of issues under the epic.

Actual Results

The progress bar shows the estimation unit used in the issues under the epic.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
