To fix the problem, remove the redundant assignment to this._indicatorElement on line 520 in the _createButtons method of js/dist/auto-complete.js. Only the second assignment (line 521) should remain, as it is sufficient to set the property. No other changes are needed, and no imports or definitions are required. The fix is a simple deletion of the first assignment.

To fix the issue, the no-op expression should either be removed entirely or replaced with meaningful code if it was intended to serve a specific purpose. Since there is no indication of its intended use, the safest approach is to remove it. This will clean up the code and eliminate the unnecessary expression without altering the existing functionality.

To fix the issue, we should remove the redundant assignment this._indicatorElement = indicator on line 559. This will eliminate the unnecessary operation without affecting the program's functionality, as the second assignment on line 560 already sets the correct value.

To fix the issue, the object literal { relatedTarget: context._element } should either be removed entirely or replaced with meaningful code if it was intended to serve a specific purpose. If the expression was meant to document the structure of an object, it should be assigned to a variable or used in a function call. Alternatively, if the value is deliberately ignored, it should be wrapped in a void expression to clarify intent.

In this case, since the object literal does not appear to serve any purpose, the best approach is to remove it entirely. This ensures the code remains clean and avoids confusion.

To fix the issue, we should remove the redundant assignment this._indicatorElement = indicator on line 627. This will eliminate the unnecessary code and ensure that the property is only assigned once, on line 628. This change does not affect the functionality of the code, as the first assignment is immediately overwritten.
