Is continuous period required from spouse visa to ILR

[manibest]

Hi

I had been granted ILR when I applied spouse visa for my wife. She will complete 5 years on spouse visa in April 2020 and will then apply for her ILR using Set(M) application form as a partner who is already settled in the UK.

Currently I am a british citizen and hold UK passport
My wife has been granted extension on her spouse visa early in January 2018
We have a daughter and she holds UK passport as well

Question: If we go out of UK and live for more than 8 months continuously, will it have any impact on my wife's ILR application.
OR will it break continuous period condition for her when she will apply for ILR in 2020?
