Build summaries fail to load on the branch list page when scrolling down far enough

Issue Summary

The branch list page shows build summary information for each branch (if build summary information exists for that branch). When scrolling down the branch list page, eventually requests to retrieve build summaries will start failing.

Steps to Reproduce

1. Create a repository with a significant number of branches (e.g. 1000+ branches)
2. Visit the branch list page with developer tools open and scroll down

Expected Results

All requests for build summaries are successful.

Actual Results

After scrolling down far enough, the requests for build-summaries will start failing with the following response:

400 java.lang.IllegalArgumentException: Request header is too large

This can be seen in e.g. browser development tools, but is not logged in the Bitbucket logs.

Build summaries will not be loaded for any branches beyond where the failed requests started.

Workaround

• Instead of scrolling down and paging, if only specific branches are of internet, the filter can be used to restrict the number of branches shown in the table.
• The server.max-http-header-size application can be used to increase the limit of the total size of HTTP headers for a single request.
