I encountered the same issue today. I might add that the problem is not specific to :active. In my case, I added a class to the element on mousedown. Devtools shows the updated cursor rule being applied, but the cursor on the screen doesn't change.

i can inconsistently repro this on chrome 62.0.3202.75 on linux. when i click on the <a> element the cursor is correct but sometimes changes back to default quickly. sometimes i need to drag the cursor to trigger this (it also changes to the drag cursor when i do this but before it changes to drag cursor it changes to default cursor).

i have forked the above codepen example (https://codepen.io/anon/pen/QOyapX) to make the <a> element larger (easier to click and drag on) as well as adding a loop to print to console the ComputedStyle value of the cursor.

as afronanny@gmail.com said the ComputedStyle is correct even when it's not being rendered correctly (see updated code pen, open dev tools and click around on a element until bug can repro, notice in the console theComptuedStyle is still correct), so this isn't a style issue.

moving to paint for triage and requesting bisect.

 

Able to reproduce this issue on reported version 62.0.3202.75, latest canary 64.0.3256.0 using Windows 10 and the issue is seen from M-50 (50.0.2641.0). Hence considering this issue as Non-Regression and marking it as Untriaged
