Sidecar files are not written when tagging from lighttable

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

When tagging multiple files from lighttable, sidecar files are not written.
This is quite annoying when tagging a lot of files. One cannot be certain that tags are not lost when copying files to a portable drive for example, or if the database is somehow corrupted.

Steps to reproduce

1. Go to lighttable and select a few files
2. Choose a tag to attach in the tagging module
3. Open the sidecar files in an editor, the tag is not there but it should be.

Choose write sidecar file from the history module for the selected files and the tags will appear in the sidecar file.

Expected behavior

Write the sidecar files immediately when setting a tag from lighttable.

No response

Start by reproducing the problem from the lighttable with several selected files, then inspect the lighttable tagging module and compare its behavior with the history module's sidecar-writing action. Done means applying a tag from lighttable immediately writes that tag to each selected file's sidecar file.
