What steps will reproduce the problem?
1. Don't have any external monitors connected
2. Open Display preferences (chrome://settings/display)
3. Drag the "Internal Display resolution" slider left or right (I can reproduce with both trackpad and touchscreen)

What is the expected result?

I'm able to select any of the screen resolutions


What happens instead of that?

The screen resolution immediately updates, which means the slider I was just dragging moves to a different point on the screen, but since the cursor didn't move, and I'm still holding down the "mouse button", that means I'm now effectively either way left or way right of the slider (depending on which way I dragged), and the slider immediately jumps to the minimum or maximum position. There's no way to pick an intermediate position using a mouse. A workaround is to click the slider to focus it, and then use the arrow keys to increase/decrease the resolution.


Please provide any additional information below. Attach a screenshot if
possible.

I hadn't noticed this issue before, and I've definitely changed the screen resolution many times before, and since I only just got 67, I think this might be a regression. I have a slight feeling that in the past, the resolution either only updated once you let go of the mouse button, or the cursor might have moved with the resolution update (keeping it the same position relative to the slider), but I can't say for sure and I don't have a 66 device to test on.

Not sure if this is an issue for external monitors as well, I don't have any around right now to test with.
