Description

This is a weird edge case but I thought I'd share it in case it's of interest.

The TeX parser turns e.g. $4.4.4$ into the number 4.4 followed by the number .4. SRE then (naturally) interprets this as an implicit multiplication which is a bit odd.

Research direction

Start by reproducing $4.4.4$ in the TeX parser and trace how it becomes 4.4 followed by .4, including SRE's implicit multiplication. The report names no source file, test, or expected alternative parse, so first establish the intended behavior with maintainers; done requires an agreed result and regression coverage.
