* Remove unnecessary stopPropagation of mathjax-overlay events * Use CodeMirror component for MathjaxHandle * Refactor ResizeObserver code in MathjaxHandle * Wrap setRange in CodeMirror in try/catch * Add Mathjax Editor bottom margin * Add custom Enter and Shift+Enter shortcuts for the MathjaxHandle * Format * Move placeCaretAfter to domlib * Move focus back to field after editing Mathjax * Put Cursor after Mathjax after accepting * Add delete button for Mathjax * Change border color of mathjax menu * Refactor into MathjaxMenu * Put caretKeyword in variable * Use one ResizeObserver for all Mathjax images * Add minmimum width for Mathjax editor * is still smaller than minimal window width * Add bazel directories to .prettierignore and format from root * exclude ftl/usage (dae) the json files that live there are output from our tooling, and formatting them means an extra step each time we want to update them also exclude .mypy_cache, which is output by scripts/mypy* * minor ftl tweak: newline -> new line (dae)
