Add frontend test suites/cases for src/components/utils

[its-me-abhishek]

some frontend components currently have less than 100% or fairly low test coverage, as visible in the coverage report (see screenshot below). this issue tracks the work required to identify and improve coverage for those components.

notes

• focus should be on meaningful tests rather than coverage-only tests
• avoid snapshot-only tests unless justified
• no functional changes are expected as part of this issue
• if interested, feel free to mention the file you are working on as a comment, and submit a PR

Hey @its-me-abhishek
I’d like to work on adding tests for ExportTasks under src/components/utils,
will open a separate PR for this file shortly.
