Breakpoint is added even when clicking on the left side of the gutter

Problem

A user reported that when using PhpStorm with the 'Breakpoints over Line Numbers' setting turned off, a breakpoint is added even if they click on the left side of the line number in the gutter. The user expected that a breakpoint would only be added when clicking on the right side of the line number.

Cause

This behavior is not a bug, but rather how the software is currently designed to function. However, the user has suggested that this design could be improved to reduce operational errors.

Resolution

The user's suggestion has been noted and a feature request has been created in our YouTrack issue tracker (Even if clicking on the left side of the line number, a breakpoint is added to the right of the line number.). The UI development and design teams are currently reviewing the ticket. They will also consider information from a related issue (New UI: not always clear where to click to put breakpoint) during their review. Any changes to the software's design will be addressed in a future release.
