Multiple matches in same line are not all highlighted

[mattia72]

Describe the bug
When searching, only the first match in a line is highlighted. If there are multiple matches on the same line, the subsequent ones are ignored.

To Reproduce
Steps to reproduce the behavior:

1. Run a search that produces multiple matches on the same line (e.g., searching for the word test in a line like test test test).
2. Observe that only the first test is highlighted.

Expected behavior
All matches in the same line should be highlighted, not just the first one.
