Update Total Votes count logic on research tab when ideas are merged

What is the challenge?

When multiple ideas are promoted or linked to the same record, the Total Votes count reflects a sum of all votes across those ideas. The challenge is that if one of those ideas is merged into the other, then the Total Votes count will double-count the votes from the merged idea.

What is the impact?

The Total Votes count inflates the actual number of total votes.

Describe your idea

If an idea is merged into another idea we should still show both of the ideas on the Research tab however, the Total Votes count should be updated to ensure votes are not double-counted.
