Research direction

The issue names no source file, test, or entry point; it provides only a screenshot and a description of reactions with appended zero-width spaces. Begin by reproducing the behavior in the relevant Element client and tracing reaction handling. Done means equivalent zero-width-space variants can no longer be used to spam reactions.
