[R-meta] equivalent random formulas but different results in rma.mv

[Timothy MacKenzie]

Dear Wolfgang,

Per https://www.metafor-project.org/doku.php/analyses:konstantopoulos2011,
I thought the following random formulas are equivalent (save for correlated
effects) leading to the same fixed effects (in my case intercept-only).

But I wonder why they produce different fixed effects?

Thanks,
Tim M
