Extra spaces inside html tags in order confirmation email template

[KarZan]

I am not quite sure if this is the correct forum section but to me it looks like the closest one

 

I have modified the ootb template from the default_bootstrap and now I have started to occasionally get emails where there are extra white spaces inside html tags. Like < /td>. I have checked and double checked that there are no extra spaces in the template. And the od thing is the space is not always in the same place and it does not happen often. Also it looks like there would be a LF also right after "<". At least it looks like it when looking at the email source.

 

Also this dis not start to happen after modifying the template but after I ticked off "Allow a customer to download and view PDF versions of his/her invoices" on order statuses.

 

And as a confirmation after checking the box on back again there hasn't been (not yet anyway) extra spaces inside html tags in the emails.

 

I do not understand why this happens? Does anyone have any similarexperiences?

 

I noticed this because the tag is visible in the email. The email looks still as it should

 

To make it more weird the emails sent to the merchant looks fine (I have email alerts module installed).
