With a model running fine with MTK v8.73.2 i run into an error with MTK v8.74.0 and also the latest v8.75. The stacktrace is attached. Since the model is little...

No documented way to set rootfind=RightRootFind in continuous Event.

In DifferentialEquations.jl one can specify the rootfind option: ```julia ContinuousCallback(condition,affect!,affect_neg!; initialize = INITIALIZE_DEFAULT, finalize = FINALIZE_DEFAULT, idxs = nothing, rootfind=LeftRootFind, save_positions=(true,true), interp_points=10, abstol=10eps(),reltol=0,repeat_nudge=1//100) ``` In ModelingToolkit.jl it is not obvious...

Instead of writing: ```julia function affect!(integ,u,p,ctx) integ.p[p.d_b1]=output[8] ``` in my old and working code, I think I have now to write: ```julia function affect!(integ,u,p,ctx) setp(integ, p.d_b1)(integ,output[8]) ``` But this gives...
