Infos about vimium compatibilty in Frameworks like Vaadin [newbie]

[KibGim]

Hello Phil,
vimium is simply outstanding.

That said, I am struggling trying to use it to highlight (Open a link in the current tab "f") inside Vaadin:
this would be very useful for many I think, especially inside dynamic frameworks with limited accessibility standards fulfilled, not keyboard-friendly.
I did research in this field but didn't find any discussion or workaround. I have deduced it could be impossible by its very nature.

For example in my case, inside a backend page of a CMS which use Vaadin, when I type "f" vimium:

• correctly recognize only eg: 8 links.
• ignore all the other links (>50).

When I type "/" and search for a string, vimium:

• correctly recognize eg: 12 occurrences.
• after clicking enter, clicking "n" (Cycle forward to the next find match) , will focus eg: only in the first 3 occurrences.

Create a new mark and go to a mark in the occurrences not cycled would help as a workaround.
But it is impossible to set a "mark" in a part of the page if it's not possible to cycle "n" or link "f" , isn't it?
(the part is written in the source code as Part_i'd_like_to_click).

Hints would be appreciated :-)
Thank you
