* copy-tex contrib module * Factor out replacement code * Fix lint * Support for more browsers, in particular Firefox * Use for loop instead of Array.forEach * Use replaceChild if replaceWith is unavailable * Browserify to remove let etc. * Fix HTML handling, in particular for Edge * Convert DocumentFragment to HTML directly (via children' outerHTML) * Set HTML content *before* text content; Edge takes the last only * Handle .katex-html and .katex-mathml separately * Implement option 2: CSS user-select: all Also fix auto-render.js build location * Revise documentation according to @kevinbarabash's comments * Split copy-tex.js into it + katex2tex.js This supports re-use of code in a custom copy handler. * Document custom copy handler * Add missing file
