The absolute-normality conjecture for the Fibonacci concatenation

The Fibonacci concatenation is the infinite sequence obtained by concatenating the Fibonacci numbers. A sequence is absolutely normal if it is normal in every integer base at least $2$.

Absolute-normality conjecture. The Fibonacci concatenation is absolutely normal.

The source gives computational evidence and explains that absolute normality would follow from normality in every base; no proof is supplied, so the conjecture remains open.
