Mail template gets modified

Sorry if I am misunderstanding but is this fix supposed to be included in the current version 1.4.0?
Because if it is, I am still facing the issue that the e-mail template isn’t being saved to the database. Even though InvoicePlane reports ‘Record successfully updated’.

Here is a link to the closed topic including the e-mail template I’m trying to use: https://community2.invoiceplane.com/t/duplicate-e-mail-template-parser-editor-injection/838

I think this is the link to the commit related to this issue: https://github.com/InvoicePlane/InvoicePlane/commit/07a181c5d1ffeeb75525ad78e6bbe2bbc397c2f8

However as I mentioned in my comment below (https://community2.invoiceplane.com/t/mail-template-gets-modified/738/21?u=flightkick) the problem stil exists for me, or it might be just another parsing issue related to my specific template.

I can also confirm that the issue still exists for me in 1.4.0. I presumed the issue was gone but didn’t have a chance to test it really. Now tested and indeed issue still exists. I also asked what exactly was wrong but no answer yet. Sooner or later this will get fixed, until that moment I’m not using the mailing function.
