Lightroom Classic: Lenses with max aperture below 1.0 not fully supported?

Question

When using a lens with a max. aperture below 1.0 (e.g. 0.95), the exif data seems to be recognized, but it's not usable in the Library Filters, in the text-bar below the histogram and also not in Smart Collections.
It seems as if the code simply doesn't support values below 1.0.
Please contact me for further details if needed.

I'm able to reproduce the problem with this test photo:
https://www.dropbox.com/s/79k5jnx3ldui97m/f95-bug-2019-09-22.jpg?dl=0

The Metadata panel and Loupe Info show f / 0.95, but:

1. The Aperture column of the Library Filter bar's Metadata browser shows Unknown Aperture.

2. The Histogram shows "-".

3. The smart-collection criterion Aperture won't let you enter a value less than f / 1.0.

As a less-convenient workaround, you could use the Any Filter plugin:

Version 9.3, an update to Lightroom Classic, went live on June 15, 2020 and contains a fix for this issue. Please install the update and respond back if it does not cure the issue for you. Thank you for your patience!

f/0.95 from the test photo in the first post now properly displays in the Filter bar's Aperture column and in the Histogram, and it can be entered into smart collections.  Tested on LR 9.3 / Mac OS 10.15.5. Thanks.
