incorrect behaviour for ctrl+(L/R)arrow

[ghost]

Description

When I try to move the cursor to the left/right using ctrl+arrow, the browser focuses the tabs on the left/right instead of moving to the previous/next word.

Steps to Reproduce

1. open 3 tabs and an website in each
2. select the 2nd tab
3. click somewhere with text
4. use ctrl+left_arrow or ctrl+right_arrow

Actual result:
If I hit ctrl+left_arrow, I focus the 1st tab.
If I hit ctrl+right_arrow, I focus the 3rd tab.

Expected result:
If I hit ctrl+left_arrow, the cursor should move to the previous word.
If I hit ctrl+right_arrow, the cursor should move to the next word.

Reproducible on current live release:
I don't know what answer I should give here becaure the brave version that eopkg (Solus package manager) and Brave display are different (0.22.810 and 0.22.727).

Additional Information

"eopkg info brave" returns brave version: 0.22.810
I use Solus 3.9999 and I have the latest updates installed.
I installed Brave from the Solus repo, not the snap package.
I think I have had this issue since I installed Brave a few months ago, so the current version of OS/kernel/browser didn't introduce it.
