Here's the code, it's quite basic and only copies over one value to the LayoutElement, but could be modified to nab other values, too: https://pastebin.com/XbvqHeCC (I don't want to do it myself because it's the long weekend - maybe tuesday!)
Can the TMP object be moved elsewhere? Curious if it's controlling position at all.
Will think more on this over the weekend, but I'd really just like to figure out... what is trying to make this move back to the origin anyway? Could it be a setting for subtitle location in AC or something...?
