@phpstorm Guys, what happened? Why PhpStorm is so slow with @bitrix24's code? I know, it's very difficult to analyze that code, but you are @jetbrains, not 1C, you can make fast applications :)
Please open the project, work there for 5 minutes (forcing it to be slow if possible), click Help | Collect and Show Logs and submit the archive within a support ticket https://intellij-support.jetbrains.com/hc/en-us
