Lightroom Auto Import importing too quickly

Hello, Classic Community!

I am experiencing an odd, intermittent (although more frequent than not) problem.  I'm shooting with a Canon EOS 90D using Canon's EOS Utility 3, with Auto Import turned on in Lightroom Classic on Windows 11.  (All version info below.)  I started noticing that Lightroom was showing my RAW and JPEG files next to each other in the grid view.  I do NOT have "Treat JPEG files next to raw files as separate photos" checked.

If I import from anywhere else, it behaves as expected (I only see one file, not the RAW and JPEG as separate files).  If I right-click on the folder and choose "Synchronize Folder...", it will let me "Remove missing photos from catalog" and it cleans everything up.

Watching the folder in Windows, it looks like the EOS utility writes the 8MB JPEG file fairly quickly (to SSD), but then takes a moment to write out the corresponding 37MB RAW file.  When watching this in Lightroom, I can see the JPG pop up, then a moment or two later the RAW file appears as well.

My theory: Lightroom is importing TOO quickly and not realizing that the RAW and JPG files are from the same shot.  It imports one, then imports the second, treating them separately.  My question: Assuming my theory is correct, is there a way to delay or otherwise convince Auto Import that the files are related?

Versions follow.  Thank you for your thoughts on this!
