File icons not rendering in the tree view of custom plugins from theia version 1.41.0 to 1.44.0

Bug Description:

File icons are not getting loading in the tree view of a custom plugin from theia version: 1.41.0 to 1.44.0.

Steps to Reproduce:

1. start theia either through source code or theia blueprint, any theia version from 1.41.0 to 1.44.0
2. install oci-core and oci-rms extensions
3. Once they are installed, you need an OCI account. you can create an OCI Free Tier account
4. Then under the OCI RMS plugin, expand the resources.
5. Notice that the file icons are not getting loaded from theia versions: 1.41.0 to 1.44..0. They are getting loaded before 1.41.0 and from 1.45.0.
6. After debugging, the result at this line matches with the result in 1.42.1 but file icons are not getting loaded.

Is it a known bug that got fixed in 1.45.0 ? Curious to know if there is any rendering not happening as expected ?

Below are the screenshots tried on Theia blueprint with theia version: 1.38.0 and 1.42.1

@planger Any idea?

Potentially related to #13213

@hyddel Could you quickly retest with 1.45 just to be sure?

[planger]

No, without debugging into it I unfortunately don't have an idea why we don't see icons here. :-/ Sorry!

@hyddel @JonasHelming I assume that this is the same issue as #13096, which has been resolved with 1.45.0. See also #13101.

The fix from #13101 did work in theia 1.42.1. Thank you so much.
