Fix T54864: Assert when changing interface display scale

The asserts were introduced on rB5f6c45498c92 (top-bar).

Although the asserts are technically correct, they would fail even in master.
And the commit simply added the asserts without fixing the situation itself
(as you can see in the report, it is really simple to reproduce this issue).

I propose we remove the asserts and bring them back only when the situation
itself is fixed. It doesn't make sense to introduce asserts that would fail
with the current state of the code.
