Then the code below worked for me.
Again, we may provide an automated check-and-repair mechanism regarding the issues above, but it's not technically interesting (and quite boring to implement), so better is to let the user prepare the input document as specified. (A simple document preset would solve this once for all.)
function fixAndDownscaleInlines( q,doc,t,wso,n,items,chars,z,c,o,aos,k,wh,xy,x,y)
//----------------------------------
// [180621] Force inline anchoring when aboveLine is found.
// [180619] Added `document.recompose()` to force smart reflow to update.
// This function proportionnaly downscale every *inline* or
// *aboveLine* anchored item found in the document, so that:
// 1. Target width does not exceed parent frame width (PFW.)
// 2. Targets whose width is *under* PFW are not touched.
// 3. Objects whose height exceeds the parent frame height (then causing
// overset issues that SmartTextReflow can't fix) are temporarily
// downscaled so that the algorithm can eat them. When available back,
// those objects are adjusted to the frame height unless width adjustment
// is required instead (to prevent them from violating rule 1.)
// Note: Smart Text Reflow must be turned on and properly set.
