Tabsize and tab support with editorconfig inside branch not working

[tkuschel]

Description

gitea version 1.20.4 (my installed version at git.kuschel.at)
gitea version 1.22.0+dev-95-gcc5df2668 (try.gitea.io)

Reproduce the issue:

1. Create a new repository, eg. "editorconfig"
2. Create a test file with tabsize = 2 (spaces), i.e.
   indent_style = tab, and indent_size = 2.
3. Commit this file to this repository (default branch),
   and push it to the gitea server.
4. The uploaded file then resides in main (or master) branch.
5. Create a new branch e.g. "issue" with "git checkout -b issue"
6. Now on the branch issue, create the file .editorconfig

# Top-most EditorConfig file
root = true
[*]
indent_style = tab
indent_size = 2
end_of_file = lf
charset = UTF-8
trim_trailing_whitespace = true
insert_final_newline = true
[*.md]
trim_trailing_whitespace = false

7. Commit and push this file to the gitea server.

Expected: View of the test_tab2 file (tabsize=2).
Received: The standard view of the gitea server, i.e.
version 1.20.4: tabsize=8
version 1.22.0-dev: tabsize=4 since #26391

8. This issue also happens with other tab sizes.

• https://git.kuschel.at/public/editorconfig/src/branch/issue

Hint: Changing the default branch to branch "issue"
recognizes the .editorconfig file!
So I think the .editorconfig file is only recognized at the default branch.

Interesting references about this topic: #26391 #24991

I would like to have a configuration option via the GUI that
can be set for the entire repository: indent style, and
indent size, similar to the .editorconfig, but without those conflicts
and knowledgement about the usage of .editorconfig
