* Edits to active plugins which cause PHP fatal errors will no longer auto-deactivate the plugin. Supersedes #39766. * Introduce sandboxed PHP file edits for active themes, preventing accidental whitescreening of a user's site when introducing a fatal error. * After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again. * Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`. * Moves file modifications from `theme-editor.php` and `plugin-editor.php` to common `wp_edit_theme_plugin_file()` function. * Refactor themes and plugin editors to submit file changes via Ajax instead of doing full page refreshes when JS is available. * Use `get` method for theme/plugin dropdowns. * Improve styling of plugin editors, including width of plugin/theme dropdowns. * Improve notices API for theme/plugin editor JS component. * Strip common base directory from plugin file list. See #24048. * Factor out functions to list editable file types in `wp_get_theme_file_editable_extensions()` and `wp_get_plugin_file_editable_extensions()`. * Scroll to line in editor that has linting error when attempting to save. See #41886. * Add checkbox to dismiss lint errors to proceed with saving. See #41887. * Only style the Update File button as disabled instead of actually disabling it for accessibility reasons. * Ensure that value from CodeMirror is used instead of `textarea` when CodeMirror is present. * Add "Are you sure?" check when leaving editor when there are unsaved changes. Supersedes [41560]. See #39766, #24048, #41886. Props westonruter, Clorith, melchoyce, johnbillion, jjj, jdgrimes, azaozz. Fixes #21622, #41887.
