Items API Initialization
enable_formula_keyboard_lazy_render
This feature has been removed as of v2025.2.LTS.
From v2025.2.LTS and onwards, the math keypad renders using SVGs instead of LaTeX, so it loads quickly by default and lazy rendering is no longer needed. The new keypad is enabled automatically and has no config parameter of its own. This feature is retained for backwards compatibility in v2025.1.LTS and earlier, where it still has an effect.
Sets whether formula and chemistry keyboards should render once an input is first focussed, rather than in the background when all other UI elements are first being rendered. This might contribute to an optimization in rendering times when there are a lot of formula or chemistry questions being rendered at once.
