PR's approval UI is not properly updated via REST API while using "Reset approvals" feature

Summary

While trying to approve a PR using REST API with "Reset approvals when the source branch of a pull request is modified" is enabled on Branch Permission, the PR's approval UI is not updated.

###Steps to Reproduce

1. Create Branch Permission with the below option checked:

• Require at least (1) approval
• Reset approvals when the source branch of a pull request is modified

1. Create a pull request
2. Use Bitbucket API to Approve PR

#!bash
curl -iX POST -u "$user:$Password" &#x27;https://api.bitbucket.org/2.0/repositories/<User>/<Repo>/pullrequests/<PRNumber>/approve

1. Refresh the PR page – approval is not displayed
2. Uncheck the "Reset approvals when the....." in the branch permission
3. Refresh the PR page – approval is displayed

###Expected Results
PR approval UI is updated after the Bitbucket API request is send

###Actual Results
Curl output shows the PR is already approved, but there're no changes on PR UI
