This commit fixes layout shifts that occur on card list part of the page
when the page is initially loaded.
- Resolve issue where card list starts with minimal width, leading
to jumps in UI until correct width is calculated on medium and
big screens.
- Dispose of existing `ResizeObserver` properly before creating a new
one. This prevents leaks and incorrect width calculations if
`containerElement` changes.
- Throttle resize events to minimize width/height calculation changes,
enhancing performance and reducing the chances for layout shifts.
Supporting CI/CD improvements:
- Enable artifact upload in CI/CD even if E2E tests fail.
- Distinguish uploaded artifacts by operating system for clarity.
This commit applies `strictNullChecks` to the entire codebase to improve
maintainability and type safety. Key changes include:
- Remove some explicit null-checks where unnecessary.
- Add necessary null-checks.
- Refactor static factory functions for a more functional approach.
- Improve some test names and contexts for better debugging.
- Add unit tests for any additional logic introduced.
- Refactor `createPositionFromRegexFullMatch` to its own function as the
logic is reused.
- Prefer `find` prefix on functions that may return `undefined` and
`get` prefix for those that always return a value.
