Flow not linting without top comment

[redeemefy]

Expected Behavior

To have errors without adding // @flow at the top of the file.

Actual Behavior

Based on Flow docs, if I set all=true I should have linting on all files.

.flowconfig

[ignore]
<PROJECT_ROOT>/.je-project-settings/.*

[include]

[libs]

[lints]

[options]
all=true

[strict]

3. Import app.js in index.html
4. Write the code I have in the screenshots
