Long pills breaks composer temporarily

Observed with `@_neb_github_=40benoit.marty=3amatrix.org:matrix.org`. Creating a pill of that user (by tap or completion) renders the composer unusable. I will attach a screenshot which illustrates if **one** pill has been created. Text can still be typed (and the pill deleted by backspace *as if* the composer were operative) but the render of the composer remains unchanged.
