Fixed: Issue with point region doesn't work in Firefox

[bsekachev]

Motivation and context

This one is probably browser issue, not CVAT.
If width or height of a SVG rectangle are 0, than getBBox() returns all 0 (even for x1, x2 which are actually not 0 according to current element attributes). Chrome works correct in this case, Firefox doesn't. Workaround-ed.

Resolved #2633

How has this been tested?

Manual testing

Yes, there is a test tests\cypress\integration\actions_users\issue_2524_issue_not_reset_after_change_task.js. I will add the issue creation as a point to it.
