sap.m.IconTabBar raises warnings when switching between tabs

[bfopta]

What is the issue and how can we reproduce it?

1. Open this icon tab bar sample
2. Switch between the tabs
3. Check the developer console

Warning:

Empty string passed to getElementById().

Expected behavior:

It probably shouldn't raise warnings.

Which OpenUI5 version is your project targeting?

1.135.0

Is the issue device- or browser-specific?

Yes, this issue only appears in Firefox, no warnings in Chrome.
Tested on windows and mac, both versions have the same issue.
