### Steps to reproduce

- In the LaTex equation block end, add “\tag{#}” to add equation number.
- When I switch to preview mode from edit mode in the same pane, some equations showed normally with equation number while some equations failed.
- More intersting is that when open preview mode in a new pane, all the equations with “\tag{#}” failed to show their numbers.

### Expected result

Each equation with “\tag{#}” can show its number.

### Actual result

- When I switch to preview mode from edit mode in the same pane, some equations showed normally with equation number while some equations failed.
- More intersting is that when open preview mode in a new pane, all the equations with “\tag{#}” failed to show their numbers.
