I am experiencing some problem when using TelerikEditor on Modal. The editor seems a bit slow and if you press enter, it doubles the next line and when you edit a text it creates a new line on it. See example below:
I was about to post with a very similar situation but I found this and thought a comment here would be more appropriate.
I don't get the enter issue mentioned, but very slow loading I do.
I've tried everything locally, and its the TelerikEditor, removing just the editor makes the window appear and load instantly, and I removed all paramters being passed down etc to isolate it.
I made a repl that has a speed issue, though its faster than what I have in my actual project... but that may just be because the repl I made is just a watered down version. The issue appears to be from using all the tools, and I think the Div editmode slows it a little also. I am using both.
The reply I made is: https://blazorrepl.telerik.com/mcEMlSQw12PUQhK134
Actual scenario I am using is similar, just a bit cleaner / more things in there etc ofc.
In general, hierarchical nesting of components might lead to a slight delay in the performance, as well as, wrapping components inside components. Therefore, putting a fully configured editor inside a window might have a slight delay due to the hierarchical nesting that the page ends up with. During my tests, the window was always opened within a second which is a negligible delay.
Regarding the double adding of the rows on an Enter press, I could not replicate it either in the REPL.
