Tests & Quizzes student scores Statistics tab not displaying colored bars for questions - column width incorrect

The Statistics tab within the the scores of a Tests & Quizzes exam should feature bars for each question answer (as in multiple choice, among others) relating how many students chose the particular option. These seem to be referred to as “progress bars” both in previous Jiras and via the JAWS screenreader, though this is a somewhat misleading moniker given that they represent either percentage correctness or percentage of total responses within the share of a question’s answers.

These bars might be used to communicate how many incorrect answers were submitted for the given question (as suggested in SAK-42179, related to this Jira) or how many students chose a particular option within a question (as suggested by the elements picked up by JAWS during testing).
