Furigana breaks sentence's parts positioning

[lyfenwebos]

For me, with mpv and enabled furigana, first several kanjis are moved at the end of the sentence when using Edge/Chrome and with Firefox parts are shuffled around when I hover the cursor over the sentence
Issue is 100% reproducible on my end.

I wasn't able to reproduce this so far, but maybe I'll come up with of something.

Another behavior that I've encountered is that 1st character is not selectable if are is not in edit mode.

Also it is reproduceable only if kamite receives text from mpv socket
When I select the exact same text by manual capture, I can select all characters, even the first one.

Is there any way to increase verbosity for me to get logs for you?

No, but the new version will change the relevant code a lot so I'll just finish that up first and see if the problem remains.
