In 2022 when I took this same trip while in Teton NP I ended up, accidentally, maybe 50 feet away from a grizzly boar, no bear spray, no where to hide except crouched down in the bush. Lucky for me he was not in a bad mood nor was he interested in me at all, although he did look back once (second shot) and sort of had a look that concerned me. I got off a couple of shots as he progressed along the path! That incident always reminds to get bear spray.

Quite an experience! I'm glad you were ok.
We had a less concerning one in Sequoia Kings Canyon NP on a mountain trail. We were descending a steep area and saw a large bear ascending the same trail towards us, displaying interest. We stepped uphill to give him the trail and to have a very minor uphill advantage. And made a lot of noise.
It continued straight towards us, nose high in the air sniffing. Eventually it stopped close enough to really hear its breathing.
I tried to make myself as large and loud as I could. My wife is pretty small. When it got to about 20 feet away and halted, head high and sniffing, I threw 6 inch diameter rocks in its direction, but not trying to hit him. I thought about tossing my backpack to it since it had food in it, but didn't have time. I was thinking that losing the backpack was better than the alternatives.
I think not backing down but letting him still have the trail led him to descend a little and rapidly go around us. The trail was by far the easiest path to follow for him up the mountain. Once it decided to leave, it was amazingly fast.
I talked to the rangers afterwards and they said we did the right thing. The wrote up the incident mainly to record how used to people bears have become. But they didn't like how interested it seemed in us. And how deliberately it approached over what seemed like a long time, but probably wasn't.
I say less concerning than your experience because it wasn't a grizzly. But it still left us pretty alarmed. I'm impressed you were able to get some photos. I probably would have thrown my camera towards the bear if I had one.
That was the most concerning bear incident I've had in a lifetime of going to the Sierras. It was also during the day whereas most other experiences were at night when they visited our backpacking campsite, which is expected and easier to prepare for.
